General thermo-mechanical behavior of composites reinforced by shape memory alloy fibers is predicted using a three-dimensional analytical micromechanical method to consider the effect of fibers activation. Composite due to the micromechanical method can be exposed to general normal and shear mechanical and thermal loading which cause to activate the shape memory alloy fibers within polymeric m...

Abstract To reduce computation time, the inherent strain (IS) method is popular. It consists in adding layers, at room temperature, with an “inherent strain” representing plastic deformation undergone during deposition. An IS developed, including a direct determination of tensor based on transient thermo-elastic-viscoplastic (TEVP) simulation. Validation achieved: taking full-field strains, all...

The dispersion analysis in a fluid filled and immersed thermo–electro elastic hollow cylinder composed of homogeneous, transversely isotropic material is studied within the frame work of linear theory of elasticity. The motions of the cylinder are formulated using the constitutive equations of a transversely isotropic piezo–thermo elastic material with a preferred material direction collinear w...

Owing to the wide acceptance of fiber reinforced composites in lightweight structure industry, need study its thermo-elastic behavior dynamical multi-body systems still remains an open question. Standard continuum models, by virtue first-order gradient deformation, cannot capture curvature effects and hence appropriate extensions standard modeling techniques are indispensable model accurate phy...

A comprehensive computational framework based on the finite element method for the simulation of coupled hygro-thermo-mechanical problems in photovoltaic laminates is herein proposed. While the thermo-mechanical problem takes place in the three-dimensional space of the laminate, moisture diffusion occurs in a two-dimensional domain represented by the polymeric layers and by the vertical channel...

In this paper, the steady-state and transient heat transfer processes of functionally graded materials (FGMs) are analyzed using a coupled thermo-mechanical model in GPU parallel multiphysics finite–discrete element software, namely MultiFracS. First, to handle problem heterogeneous is verified. Then, advantages disadvantages FGMs composite response thermal shock loads compared results indicate...

The high average power laser (HAPL) program goal is to develop a laser inertial fusion reactor using a solid first wall (FW). The FW of the inertial fusion energy (IFE) chamber is exposed to high energy photon, particle, and neutron fluxes at frequency of several Hz. The feasibility of using a micro-engineered refractory metals, such as tungsten foam as a solid FW armor is investigated. Refract...

Abstract Studies of host rock deformation around magmatic intrusions usually focus on the development stresses directly related to intrusion process. This is done either by considering an inflating region that represents intruding body, or multiphase deformation. Thermal processes, especially volume changes caused thermal expansion are typically ignored. We show upper crustal magma bodies likel...
