PurposeThe vibration characteristics of the beam depend upon its uniformity, material density, and presence of any defects like cracks. The present study investigated the vibration characteristics of a cracked cantilever beam comprised of structural steel and E-glass fiber using ANSYS 18.1 FEA software.Method The effect of crack parameters, such as...

PurposeThe aim of this paper is to quantify the stochastic effect for functionally graded (FG) plate in conjunction to free vibration and impact loading.Method The variabilities in geometric and materials properties are considered. A support vector machine (SVM) is employed to construct the surrogate model. The constructed model portrays significan...
Chapter
Stochastic first-ply failure analysis of a carbon-epoxy-based laminated composite plate is conducted based on Monte Carlo simulation (MCS) and moving least squares (MLS)-based surrogate model. A five-noded finite element (FE) model is developed to determine the deterministic first-ply failure load. The inherited randomness in the geometrical proper...

Purpose: This paper presents the sensitivity analysis (SA) of the random natural frequency responses of hybrid multi-functionally graded sandwich (HMGS) shells for establishing a unified measure in the case of multi-objective performances. The functionally graded materials, laminated composites, and sandwich cores are employed to develop such novel...
Article
In structural applications, laminated composites are typically the best choice for providing a high strength-to-weight ratio. The composite laminates, on the other hand, are susceptible to the first ply failure (FPF), which can result in delamination, matrix cracking, and fibre breaking. As a result, it's critical to map the FPF of laminated compos...
Article
The present paper proposes a surrogate-assisted moment-independent stochastic sensitivity analysis of laminated composite plates for establishing a unified measure in the case of multi-objective performances. With the advancements in artificially engineered structural systems spanning across different length scales, it has become more common to des...
Chapter
In the present chapter, multivariate adaptive regression splines (MARS) is explored as a surrogate model in conjunction to Monte Carlo simulation (MCS) to analyse the random first-ply failure loads of graphite–epoxy laminated composite plates. The five failure criteria, namely maximum strain theory, maximum stress theory, Tsai–Hill theory, Tsai–Wu...
Chapter
Full-text available
This paper presents the random first-ply failure analyses of laminated composite plates by using an artificial neural network (ANN)-based surrogate model. In general, materials and geometric uncertainties are unavoidable in such structures due to their inherent anisotropy and randomness in system configuration. To map such variabilities, stochastic...
Chapter
Full-text available
This paper presents the first-ply failure analysis of laminated composite spherical shells by using the finite element method (FEM) in conjunction with Monte Carlo Simulation (MCS) approach. The material and geometric uncertainties caused by anisotropy and randomness inherent in the system configuration are predetermined in such structures and dema...
