Recently various nanomaterials, such as carbon nanotubes and graphene, have been added to rubbery elastomers, such as poly dimethyl siloxane (PDMS), to enable generation of stress and displacement in response to remote illumination. While the response is primarily due to heat-induced generation of stress; i.e., the thermoelastic effect in rubbers, illuminated samples have shown unexpected devia...

The wave propagation in viscothermoelastic materials is discussed the present work using nonlocal thermoelasticity model.

Eringen’s theory continuum. linear Kelvin–Voigt viscoelasticity explains viscoelastic properties isotropic material. analytical...

This article presents an experimental study on the fatigue behaviour of cracks emanating from cold-expanded holes utilizing thermoelastic stress analysis (TSA) and synchrotron X-ray diffraction (SXRD) techniques with the aim of resolving the long-standing ambiguity in the literature regarding potential relaxation, or modification, of beneficial compressive residual stresses as a result of fatig...

The term thermal stresses are related to mechanics of materials. stress is formed due any changes in temperature a material. large change concludes higher the stresses. Also, there an effect expansion coefficient on different for In present paper, design mathematical model concerning hollow cylinder subject heat conduction with initial and boundary conditions have developed. basic aim this work...

We consider the stability properties for thermoelastic Bresse system which describes the motion of a linear planar shearable thermoelastic beam. The system consists of three wave equations and two heat equations coupled in certain pattern. The two wave equations about the longitudinal displacement and shear angle displacement are effectively damped by the dissipation from the two heat equations...

In this work, an analytical solution for thermoelastic waves in a metal induced by an ultrafast laser pulse was formulated in the form of a Fourier series. The two-step heat transfer model was applied to account for the thermal nonequilibrium between electrons and the lattice during ultrafast pulsed laser heating. The coupling between the strain rate and the temperature ®eld was also considered...

We analyze axisymmetric deformations of a rotating disk with its thickness, mass density, thermal expansion coefficient and shear modulus varying in the radial direction. The disk is made of a rubberlike material that is modeled as isotropic, linear thermoelastic and incompressible. We note that the hydrostatic pressure in the constitutive relation of the material is to be determined as a part ...

Introduction Composite materials are weak normal to the plane of the laminate due to a lack of through-thickness reinforcement, with strength dictated by the brittle epoxy matrix. Therefore it is important to evaluate the through-thickness load transfer in composite bonded joints because of their discontinuous nature to improve confidence in the join and inform more efficient joint designs. A d...

In shape memory alloys the Thermoelastic Martensitic Transformation (TMT), intrinsically stepwise, can be either thermally induced or stress-induced. Moreover, it has already been shown that an extrinsic fragmentation of thermally induced transformation can be stimulated ("Step-wise Martensite to Austenite Reversible Transformation", SMART) by means of Incomplete Cycles on Heating (ICHs): the S...
