Three-dimensional quasi-static general solution for isotropic thermoelastic medium with applications
Case Studies in Thermal Engineering, 2021 An accurate and efficient method for three dimensional quasi-static thermal elastic problems is established. The three-dimensional equations of isotropic quasi-static-thermo-elasticity are simplified by the introduction of two displacement functions.

A peridynamics-based finite element method for quasi-static fracture analysis
CoRR, 2021 In this paper, a peridynamics-based finite element method (Peri-FEM) is proposed for the quasi-static fracture analysis, which is of the consistent computational framework with the classical finite element method (FEM). First, the integral domain of the peridynamics is reconstructed, and a new type of element called peridynamic element (PE) is defined.
