We report here the ionic conductivity characteristics of single crystal of Yttria Stabilized Zirconia (YSZ) < 100 > . The targets of YSZ of one-inch diameter and about 2-3 mm thickness were palletized and sintered in the range of 1000- 15000 C for 2-4 hours in air. These targets were polished up to 1000 emery paper cleaned in an ultrasonic bath con...
The research paper focuses on the Topology optimization by the objective of optimizing/reducing unsprung weight in the form of alloy wheel, ultimately which leads to weight reduction of a four wheeler for the vehicular applications. The weight of the Automobile is one of the most important factor that affecting fuel economy. Rim wheels plays a sign...
Friction welding (FW) has emerged as a promising approach for joining materials that are traditionally difficult to weld together due to their distinct properties. This research delves into the optimization of FW parameters for joining two commercial materials: Stainless Steel (SS) and Mild Steel (EN3B). This study investigates the optimization of...
The manufacturing industry has witnessed substantial interest in the advancement of 4D printing technology in recent years. This technology has enabled the production of complex structures with enhanced functionality and adaptability. Fused Deposition Modeling (FDM) has become a preferred technique for 4D printing due to its ease of use, affordabil...
The study aims to optimize the shape change response of the Shape Memory Photopolymer Composites (SMPPCs) through the use of the Taguchi method. The SMPPCs were created by blending of Soft Photopolymer Resin (SPPR) with Hard Photopolymer Resin (HPPR) in various weight fractions and reinforcing with Silica Nanoparticles (SNPs) at different weight pe...
In their quest to develop lightweight biodegradable materials for automobile applications, researchers have been pushed to replace synthetic fibers with natural fibers to a large extent. As a result, an experimental study is conducted to assess the implications of stacking configuration, secondary reinforcement and graphite loading on the mechanica...
Purpose
Shape memory materials are functional materials having a good number of applications due to their unique features of programmable material technology such as self-stretching, self-assembly and self-tightening. Advancements in today’s technology led to the easy fabrication of such novel materials using 3D printing techniques. When an externa...
Purpose
The tear strength (Ts) is a significant property for any kind of soft polymeric material such as rubber, elastomer, viscoelastic material and its composites, to quantify the suitability of a material for any shape memory applications. Many times, the soft elastomeric polymer material has to be capable enough to deform to a maximum extent of...
Aluminium has its vital role to play in engineering materials for producing higher strength-to-weight ratio components. In this present research, the tribological properties of aluminium alloy AA7075 strengthened by Tungsten Carbide (WC) at different proportions (1 and 2% wt. of WC) are synthesised using stir- casting method. To measure wear and fr...
Purpose:
Masked stereolithography (MSLA) or resin three-dimensional (3D) printing is one of the most extensively used high-resolution additive manufacturing technologies. Even though, the quality of 3D printing is determined by several factors, including the equipment, materials and slicer. Besides, the layer height, print orientation and exposure...
Quest for producing lightweight and biodegradable materials has encouraged researchers to replace synthetic fibers with natural fibers. Hence a study is made to investigate the effects of introducing secondary reinforcement (natural fibers), stacking sequence, and addition of graphite particles on the mechanical characteristics and water uptakes al...
Resin 3-Dimensional (3D) printing technology is known for complex parts with fine features and accurate dimensions for its high quality, high-resolution. The ability to print dimensionally accurate parts, depends on equipment, materials and slicer, few of which are layer height, orientation, and exposure time. The modern technology allows designers...

Continuous fiber-reinforced polymer composite materials fabrication using additive
manufacturing (AM) technology like 3D printing is an active research area to
be taken up. The research not only focuses on the determination of mechanical,
electrical, and thermal properties of a component but also enhancing the same
individual or in a combination of...
Modern machining processes are become excessive dependent to meet with common needs of modernization in civilization. In this attempt EDM is taken up in to primary consideration as it is sharing prominent role in the entity of modern machining processes. It was observed that the salient feature like high energy generation for highly sophisticated s...

I am confused with nano reinforced SMPCs, Can anyone help me in explaining about role of nano reinforcement in SMPCs.
Many research articles are stating about PLA as one of the SMPs, Can anyone explain me the reasons.
As a part of my research i am confused in between terns SMP and elastomer.
I want to know which is best SLA 3D printing photo polymer resin for preparing nano reinforced polymer composite and is it possible to prepare our own photo polymer resin or not. Please give your valuable suggestions. Thank you.
I want to start my research work on nano reinforced polymer composites, for that i am choosing desktop SLA additive manufacturing process for preparing the component. My doubt is that, is it possible to cross link the photo polymer which is reinforced with nano particles. If it is possible, then how extent will it give better performance? If not possible, then what is the alternative method to reinforce photo polymer to get better performance? Please respond, your suggestions will helps me a lot to go in right direction.
Hello everyone,
I have done RVE simulation of nano-sized particulate polymer composite for the different volume fractions of 0 to 40% and the different size of the particles of 1 nm to 100's of nm in COMSOL. Anyway, I am getting the effective modulus variations for volume fraction change only not for the particle size. Based on the literature of experimental data, particle size effect is there in polymer composites. Everyone knows well that particle size effect is there because at nano size particle behavior may change. So can anyone give suggestions for me? Looking for the fruitful information. Thank you.
In DIGIMAT I want to prepare RVE in digimat for epoxy matrix and E-glass fiber so that i given materials properties, microstructure correctly but coming to RVE section after adding fabric it showing this error. I am not understanding how to solve and get proper RVE. For the reference i am attaching the screenshot of the error, please look into this and any one help me out of this error.
Thank you.
