“…r The second perspective is the extension towards to the nonlinear case as it has been done in some special case of the mid-point rule in [5,29,47]. Using the special form of the gyroscopic forces if the mass matrix depends on q and the fact that some forces derived from a smooth potential, we may use the discrete derivative introduced in [25] to extend the result of the paper in a nonlinear setting.…”

“…The numerical scheme (25) has been designed such that it deals, as the Moreau-Jean scheme with the contact forces and impact through their associated impulses P k+1 in a fully implicit way. In this manner, we ensure that the scheme will be consistent when the time-step vanishes if an impact occurs.…”

“…cT ik 1T D 0 and ik 1T D ik 2T D 0 because there is no penalty spring in the tangential direction, see the slip condition in Equation (25). Therefore, the equation that provides the infinite (therefore undetermined) relations between ik 1N , ik 2N is:…”

“…However, this property is linked specifically to linear elasticity with quadratic strains. An important extension of the energy conservation algorithms to more general nonlinear problems was made by Gonzalez [15,16], who generalized the representation of the internal force to include an additive discrete energy gradient term, much in the vein of the gradient representation in optimization algorithms, [17]. An early scalar version of the secant style conservative integration was presented by Greenspan [18], and discrete gradient integrations methods have been developed for classic mechanics [19], nonlinear elasticity [20], multibody dynamics [21], and mathematical physics [22].In the energy-momentum approach, the algorithms are typically formulated for an undamped system.…”
