Abstract: In this paper, a study is made of the flexural, elastic-wave propagation and vibration of laminated rods and beams of sandwich construction. The problem is treated two-dimensionally, and the ...

Abstract: The behavior of sand on the

Abstract: A comprehensive understanding of the shear behavior of sand in the context of shear band development has not been achieved yet in spite of many detailed research works on each specified subject. In order to observe the ...

Abstract: This study presents the influence of the interparticle friction angle on the cyclic behavior of granular materials using the two-dimensional (2D) discrete-element method (DEM). The numerical sample was modeled with oval-shaped ...

Abstract: Discrete element method (DEM) simulations are used for measuring the macroscale and microscale changes in stress and fabric for the cyclic loading of a two-dimensional granular assembly. The stress–strain–dilatancy tendencies ...

Abstract: The discrete-element method (DEM) is an important tool for understanding the underlying microscale processes that influence macroscale behavior. For quasi-static simulations, numerically imaginary input parameters such as ...

Abstract: The influence of the intermediate stress ratio on the mechanical behavior of granular materials under generalized stress conditions is not well understood, particularly in regard to relationships between macroscale behavior ...

Abstract: It is well known that the resistance to liquefaction of a saturated sand decreases sharply when it has been presheared, either cyclically or quasi statically, beyond a threshold value. The possible mechanism is discussed ...
