Abstract: This talk addresses non-smooth contact formulations for multibody systems with unilateral constraints and frictional interactions. Applications span granular materials, robotic manipulation, videogames, real-time simulators, AI, automation, and complex mechanical assemblies in general. The presentation covers theoretical foundations of non-smooth dynamics based on complementarity problems and measure differential inclusions. State of the art collision detection methods will be presented too. Efficient numerical methods including cone complementarity problem (CCP) solvers and primal-dual interior point algorithms for large-scale rigid body assemblies will be introduced, highlighting limitations and open problems. Special attention will be given to matrix-free iterative techniques enabling simulation of systems with millions of contacting bodies. Practical implementation challenges in high-performance computing environments and GPU acceleration will be discussed. Recent advances in Anderson-accelerated fixed-point methods for solving non-smooth contact problems will be presented. Future perspectives include tighter integration of non-smooth dynamics with machine learning, especially for robotic control.
