The Shen Yongxing Research Group of the University of Michigan at Jiaotong University realized the asynchronous solution of the dynamic fracture problem

Recently, the team of Shen Yongxing of the Michigan Institute of Shanghai Jiao Tong University published an online report entitled "An asynchronous variational integrator for the phase field approach to dynamic fracture" in the International Journal for Numerical Methods in Engineering, a top journal in the field of computational mechanics (a method of nonsynchronous variational integral for solving dynamic fractured phase fields) research paper
.

Partial dynamic crack propagation path phase field result, where 1 indicates complete fracture of the material and 0 indicates intact

Fracture mechanics is a discipline that studies the law of crack propagation in materials and structures
.

In order to improve the computational efficiency, Shen Yongxing's research team adopted a non-synchronous algorithm, that is, to solve local information
non-synchronously without violating the law of causality.
