Implicit and explicit time integration schemes in conjunction with the finite element method are presented for the transient response of highly non-linear problems such as impact situations exhibiting important material dissipation. Surprisingly the implicit schemes lead to excellent convergence properties that make them a cost-efficient alternative to explicit scheme generally advocated as the best choice for these problems. As numerical illustrations, we present here the academic impact between two flexible bodies, a long tube and a long plate, as well as a more industrial-oriented application: the impact between a fan blade and a double casing.
