The Schwarz alternating method for transient solid dynamics

International Journal for Numerical Methods in Engineering, 2022
In our earlier work, we formulated the Schwarz alternating method as a means for concurrent multiscale coupling in finite deformation solid mechanics for quasi‐static problems.

A finite element formulation in boundary representation for the analysis of nonlinear problems in solid mechanics

Computer Methods in Applied Mechanics and Engineering, 2018
The contribution is concerned with a numerical element formulation for the analysis of the nonlinear behavior in solid mechanics. It is based on the so‐called scaled boundary finite element method (SB‐FEM).

Enriched three-field numerical manifold formulation for dynamics of fractured saturated porous media

Computer Methods in Applied Mechanics and Engineering, 2019
In terms of the three-field (u-w-p) formulation of Biot’s theory of saturated porous media with incompressible solid and fluid phases, the numerical manifold method (NMM) models are developed to analyze the fully dynamic consolidation of fractured porous

Learning the Solution Operator Family in Elastic Mechanics for Response Prediction Under Various Load Scenarios

International Journal for Numerical Methods in Engineering
Analyzing the responses of solid materials under diverse loading scenarios with different types and forms is a fundamental engineering necessity. However, a load‐adaptable machine learning model that can predict such responses still needs to be explored.
