High precision solution for thermo-elastic equations using stable node-based smoothed finite element method

作者：

Highlights：

• The stable node-based smoothed finite element method (SNS-FEM) is presented to solve thermo-elastic equations.

• The SNS-FEM can achieve higher accuracy in displacement.

• Von Mises stress computed by the SNS-FEM is very accurate especially in high stress zones.

• The SNS-FEM is more efficient than the FEM and original NS-FEM.
