Modeling and analysis of planar rigid multibody systems with translational clearance joints based on the nonsmooth dynamics approach

Analysis of a generalized kinematic impact law for multibody-multicontact systems, with application to the planar rocking block and chains of balls

“…A similar model with E n =diag(e n,i ) and Coulomb friction at the impulse level is also used in [5,[16][17][18]. Same conclusions hold for impact laws with friction as studied in [49], among others.…”

On the continuous contact force models for soft materials in multibody dynamics

“…The contact problem has been an intensive topic of research over the last decades and deserved the attention of many authors, which led to the development of relevant work and even to the publication of a good number of textbooks totally devoted to this issue, such as those by Goldsmith [4], Brach [5], Pfeiffer and Glocker [6], Johnson [7], Stronge [8], Wriggers [9], among others. The contactimpact study in multibody dynamics has received a great deal of attention in the past few years and it still remains an active field of research and development [10][11][12][13][14][15][16][17][18][19][20][21][22].…”

A review of friction models in interacting joints for durability design

“…[121]. Other solution methods include differential variation inequality (DVI) and Moreau's time stepping algorithm [21,121].…”

“…However the limitation in Ref. [121] can be overcome by choosing appropriate friction and degree of nonlinearity for complex contact conditions. In addition, the problem of energy dissipation without violating the energy conservation condition is critical since even for low energy impacts, energy is transformed into sound and mechanical vibrations, as a function of the coefficient of restitution whose definition is subjective.…”
