Abstract Ambient cured epoxy adhesive is widely used for bonding fibre reinforced polymer (FRP) plates to metallic structures. The present paper examines a typical strengthening investigate the effect of thermo-viscoelasticity. response was determined using series tests multi-frequency scanning mode dynamic mechanical analyser (DMA). thermo-mechanical properties were then characterised time–tem...

This paper presents the first results obtained in a facility constructed at the University of California, Los Angeles to study the interaction of ceramic breeder pebble beds with structural materials in conditions relevant to fusion energy power plant blanket operations. The experiments study the thermo-mechanical performance of lithium meta-titanate oxide (Li2TiO3) pebbles and silicon carbide ...

Electro-magneto-thermo-elastic response of a thick double-layered cylinder made from a homogeneous interlayer and a functionally graded piezoelectric material (FGPM) outer layer is investigated. Material properties of the FGPM layer vary along radius based on the power law distribution. The vessel is subjected to an internal pressure, an induced electric potential, a uniform magnetic field and ...

Introduction The wave propagation in magneto-electro-elastic materials has gained considerable importance since last decade. The electro-magneto-elastic materials exhibit a desirable coupling effect between electric and magnetic fields, which are useful in smart structure applications. These materials have the capacity to convert one form of energy namely, magnetic, electric and mechanical ener...

The aim of this work is to propose a new numerical method for solving the mechanical frictional contact problem in the general case of multi-bodies in a three dimensional space. This method is called adapted augmented Lagrangian method (AALM) and can be used in a multi-physical context (like thermo-electro-mechanical fields problems). This paper presents this new method and its advantages over ...

Abstract Additive manufacturing (AM) techniques represent a real challenge to manufacture novel composites with coupled multifunctional properties. This work focuses on the mechanical, electrical and thermal behaviours of 3D printed polymeric polylactic acid (PLA) filled carbon black (CB) conductive particles . The incorporation within polymer matrix allows for programmable conduction paths via...

Even under normal operating conditions, power devices are subject to temperature changes that generate high level of stress repeatedly causes mechanical breakdown. In this context thermomechanical simulations are necessary to predict life time and guarantee a longer lifespan. This paper aims to modeling electro-thermo-mechanical behavior of a vertical power transistor for predicting the influen...

Abstract In the present research, a numerical modeling approach of initial stage consolidation during spark plasma sintering on microscopic scale is presented. The solution fully coupled thermo-electro-mechanical problem also accounting for grain boundary and surface diffusion found by using staggered way. finite-element method applied solving while finite-difference problem. A Lagrange-based n...
