Dear All,
As FEA is one of the most popular methods for the treatment of contact problems. In that, the overall contact surface is discretized a number of segments and contact integrals are evaluated in a segment-wise manner. In 2005 Fischer and Wriggers [1] presented an integration method which avoids the need of contact surface segmentations and enables the evaluation of contact integrals directly at the slave nodes of contact bodies.
However, I couldn't follow the integration approach presented in [1]. Therefore, seeking help if you could help or suggest me to be able to implement the same in my code.
Thanks in advance.
Best regards,
Vishal Agrawal
