As the most common fastening method in mechanical engineering, the mechanical properties of bolted connections are crucial to the overall safety and reliability of the structure. In practice, the ...

Based on a new elastic clump model, a flexible membrane is proposed for the discrete element numerical simulations of triaxial tests. Conversional triaxial tests of sandstone under the confining ...

Professor of Mechanics, Washington University, St. Louis, Mo. It's easy to construct finite-element models with errors. And it's just as easy to correct them, when you know how. The first step in a ...

Second-order shell elements: Meshing the thin band with secondorder-shell elements produces precise curvilinear geometry. There was a time when the task of building a model for finite-element analysis ...
