Regarding implementation of an integration scheme which avoids the need of contact surface segmentation.

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
