A sharp interface method for an immersed viscoelastic solid

•The method resolves pressure jumps in immersed boundary finite element formulations.•The formulation applies to solids undergoing large deformations.•Pointwise convergence of the pressure field is observed in most cases.•The method is tested on benchmark problems with zero and nonzero velocity fiel...
