Estimation of the viscoelastic properties of rubber bushings at very high frequencies (up to 2 kHz) is a challenge for many damping component manufacturers in the design stage of a quality monitoring procedure. This investigation is focused on the capability of lower strain rate testing procedures, such as relaxation tests, to estimate and extrapol...
The Small Punch Creep-Recovery Test (SPCRT) is a novel miniature test used to estimate the viscoelastic properties of polymers and biomaterials. The current investigation related to the SPCRT is limited to Finite Element Method (FEM) simulations and experimental tests on PVC. The aim of this investigation was focused on: (i) extending the experimen...
The tubes and pipes manufacturing industry characterizes the mechanical properties of their products with a wide selection of standards, but most of them are qualitative testing methodologies. To estimate the mechanical properties from a quantitative point of view there are limited options in standards. In that sense, the standard tensile test is t...
Research on the Small Punch Test (SPT) has been mainly focused on metallic alloys, with limited investigations in polymeric materials. The miniature size of the SPT eases and motivates its use in biomedical applications, like the mechanical characterization of surgical implants made of different polymers. It is noted that the aim of these publicati...
During the twentieth century many investigations have been published about the reliability of the multiple-choice tests for subject evaluation. Specifically, there are a lot of theoretical and empirical studies that compare the different scoring methods applied in tests. A novel algorithm was designed to generate hypothetical examinees with three s...
The Small Punch Test (SPT) has aroused interest in the last years as a mechanical characterization test due to its simple geometry and the minimum required specimen volume. Its origin in the nuclear industry has motivated wide research focused on the evaluation of ferrous alloys, and there are few publications for other materials like non-ferrous a...
Cold expansion technology is an extended method used in aeronautics to increase fatigue life of holes and hence extending inspection intervals. During the cold expansion process, a mechanical mandrel is forced to pass along the hole generating compressive residual hoop stresses. The most widely accepted geometry for this mandrel is the tapered one...
There is a growing interest on the Small Punch Test (SPT) and its many applications in a broad range of industries and sectors. The miniature volume of the SPT specimen eases the mechanical characterization of components and structures when standard tests are impracticable. But this miniature test is limited for one of its more constraining require...
The Small Punch Test (SPT) was developed in the 80's as an alternative miniature test for the characterization of mechanical properties in the nuclear industry. One of the key aspects that materials must fulfill to be used with this miniature test is that of homogeneity and isotropy. The origin of the isotropy requirement comes from the fact that t...
The Small Punch Test (SPT) was developed as an alternative test to evaluate the mechanical properties of materials from a small material volume. Although the SPT is close to its standardization as a mechanical testing method, there are many methodologies for the estimation of the different mechanical properties. All of them are based on the use of...
Cold expansion technology is a cold-forming process widely used in aeronautics to extend the fatigue life of riveted and bolted holes. During this process, an oversized mandrel is pushed through the hole in order to yield it and generate compressive residual stresses contributing to the fatigue life extension of the hole. In this paper, a parametri...
Small Punch Test (SPT) is a miniature mechanical characterization test used as an alternative method to obtain a wide selection of mechanical properties (modulus of elasticity, yield strength, ultimate tensile strength, fracture toughness, etc). The miniature size inherent to SPT allows their application to hot-stamped forming processes in the auto...
El ensayo miniatura de punzonado se ha utilizado, entre otras cosas, para la caracterización de las propiedades mecánicas inherentes al ensayo estándar de tracción uniaxial. Uno de los principales problemas que muestra este ensayo es su alto nivel de dispersión al incluir en la regresión una alta variedad de materiales. Siempre se ha considerado qu...
During creep, magnesium alloys undergo microstructural changes due to temperature and stress. These alterations are associated with the evolution of the present phases at a microstructural level, creating different strain rates during primary and tertiary creep, and with the stability of the inter-metallic phase Mg17Al12 formed at these temperature...
The Small Punch Test (SPT) is a miniature mechanical characterization test used as an alternative method to obtain a wide selection of mechanical properties (Young's modulus, yield strength, ultimate tensile strength, fracture toughness, etc). These mechanical properties are obtained in the SPT from correlations with different data of the load-disp...
This study was focused on a metallic part from a dynamic seal of an ultra-high pressure intensifier. This part developed cracks originated at pressure relieving slots. Cracks were analyzed to get information about their origin and propagation mechanisms Simulations were performed to derive stress and strain state near the initiation region. It was...
Nacido de la necesidad de reducir el tamaño de las probetas de ensayo para caracterizar el efecto de la radiación en los materiales que componían las vasijas nucleares, el ensayo miniatura de punzonado (SPT) ha mostrado una evolución metodológica que ha ampliado su aplicación a
amplios sectores industriales y a una cada vez más diversa familia de...
The load–deflection curve acquired from the Small Punch Test (SPT) is used to obtain the mechanical properties of materials using different correlation methods. The scattering level of these regressions tends to be high when a wide set of materials is analyzed. In this study, a correlation method based on a specific slope of the SPT curve was propo...
The Small Punch Test (SPT) is a miniaturized test to characterize the mechanical properties of the materials. The load-displacement curve obtained by this test does not directly provide the material parameters, and linear correlations between data obtained from SPT curve and each mechanical property are necessary. The main difficulty of these corre...

El ensayo miniatura de punzonado (SPT) se utiliza para la obtención de propiedades mecánicas de materiales a partir de una correlación lineal previa entre datos extraídos de la curva carga-desplazamiento del SPT y ensayos de tracción uniaxial.

Generally, the correlation factors of parameters obtained from the load-displacement curve of small punch tests and the mechanical properties of materials are only acceptable for the materials tested in each investigation. Although the standardization of the correlation factors for different groups of materials is the objective in much of the resea...

Los tratamientos criogénicos no tienen más de un siglo de historia y ya han suscitado en fabricantes y académicos pensamientos antagónicos de esperanza, perspectiva, desilusión y recelo. Su evolución está jalonada por tristes épocas de investigaciones con resultados manipulados o incoherentes, y otros momentos de profunda indagación científica que...
