Nonlinear FEA for soft robots
Contact interaction plays a major role in implementing physical phenomenon in countless fields requiring a very precise solution. In particular, soft robots which produce various motion using the flexibility of continuous structure have more complicate contact interaction. Therefore, if such a mechanical system is interpreted as a full 3D model, it requires a lot of computational cost due to its high nonlinearity and complex geometry. Beam to beam contact is good simulation model to overcome this limitation and achieve real-time analysis.
