The neighbored element method for damage processes at large deformations

The neighbored element method for damage processes at large deformations

Led by:  P. Junker
Year:  2021

The developed damage model was extended for the treatment of hyperelastic material subjected to large deformations. Along with the model derivation, a technique for element erosion in the case of severely damaged materials was also developed. Numerical results showed convergence for different mesh sizes and increasing regularization parameter. Efficiency and robustness of the approach is demonstrated by numerical examples including snapback and springback phenomena.
