Adaptive finite element analysis of free vibration of elastic membranes via element energy projection technique

Haohan Sun, Si Yuan

A general strategy is developed for adaptive finite element (FE) analysis of free vibration of elastic membranes based on the element energy projection (EEP) technique.

On the topological enrichment for crack modeling via the generalized/extended FEM: a novel discussion considering smooth partitions of unity

Diego Amadeu F. Torres

It has been usual to prefer an enrichment pattern independent of the mesh when applying singular functions in the Generalized/eXtended finite element method (G/XFEM). This choice…

Jiao Wang

This paper aims to propose an efficient and convenient numerical algorithm for two-dimensional nonlinear Volterra-Fredholm integral equations and fractional integro-differential…

Computational predictions for predicting the performance of steel 1 panel shear wall under explosive loads

Aydin Shishegaran, Behnam Karami, Elham Safari Danalou, Hesam Varaee, Timon Rabczuk

The resistance of steel plate shear walls (SPSW) under explosive loads is evaluated using nonlinear FE analysis and surrogate methods. This study uses the conventional weapons…

Design modification of iron ore bearing transfer chute using discrete element method

Saprativ Basu, Arijit Chakrabarty, Samik Nag, Kishore Behera, Brati Bandyopadhyay, Andrew Phillip Grima, Probal Ghosh
