Abstract: The present paper deals with theoretical and computational analysis of quasi-static, normal indentation of a transversely isotropic, linear elastic, piezoelectric half-space by a rigid spherical ...

Abstract: Plane-strain contact analysis is presented for compositionally graded materials with power-law strain hardening. The half-space, y ≤ 0, is modeled as an incompressible, nonlinear elastic material. ...

Abstract: The present work examines the influence of pre-existing, elastic surface stresses on instrumented sharp indentation. The surface is modeled as a homogeneous and isotropic elastoplastic solid in ...

Abstract: In the present work, the propagation of elasto-damage longitudinal stress waves in thin rods is investigated. The material behavior is characteristic to that of certain monolithic ceramics. The ...

Abstract: It is shown here that the shielding effect of a distribution of microcracks, i.e., the extent to which they alleviate the severity of a near-tip singular field, is maximized when the microcracks ...

Abstract: The present paper presents a relation between the vickers hardness HV and the loading stiffness C of instrumented vickers indentation of metal substrates. The relation is based on the fact ...

Abstract: In recent years functionally-graded composites have been proposed to develop strong surfaces that can withstand high contact and frictional forces. The present work presents a new graded composite ...

Abstract: Functionally graded materials (FGMs) are composite materials that exhibit a microstructure that varies locally in order to achieve a specific type of local material properties distribution. In ...

Abstract: A technical theory for pretwisted beams that accounts for variable twist (constrained warping) is based on an approximate displacement field that is defined completely in terms of two unknown functions: the axial displacement
