The stochastic response of a rigid platform is quasi-static and can be represented as a linear combination of nonlinear random wave loadings. In this study two efficient probabilistic approaches are respectively presented to estimate the higher-[...]

Basin-scale internal waves are inherently nonhydrostatic; however, they are frequently resolved features in three-dimensional hydrostatic lake and coastal ocean models. Comparison of hydrostatic and nonhydrostatic formulations of the Centre for [...]

In this paper a consistent method including damage criteria in the seismic response of single-degree-of-freedom systems is proposed. The method allows the determination of suitably modified strength or displacement inelastic spectra through the [...]

An efficient method is presented to characterize the damage state for two-dimensional multicracked elastic solids. This method is based on the concept of a path-independent Mc-integral, through which the surface energy associated with creation o[...]

A three-dimensional (3D) micromechanics-based evolutionary damage model is proposed to predict the effective elastic behavior of continuous fiber-reinforced brittle matrix composites with microcracks and imperfect interfaces. Eshelby's tensor fo[...]

The paper investigates the characteristics of propagating shock waves in soil, resulting from an explosion of a cylindrical line charge. The main purpose of this investigation is to study the full locking parameter's effect on the qualitative an[...]

Asymptotic theories of classical micromechanics are built on a fundamental assumption of large separation of scales. For random heterogeneous materials the scale-decoupling assumption however is inapplicable in many circumstances from convention[...]

A vast amount of indentation studies on coating/substrate systems focused on extracting the mechanical properties of the film, by either avoiding or subtracting off the substrate effect. However, in engineering and biomedical applications, very [...]

In this paper, a new method capable of predicting the critical deformation of composite materials with interfacial cracks is presented under mixed mode conditions using stress intensity factors K1 and K2 and the fracture criteria of the interfac[...]
