Abstract
This study presents the analysis of the planar mechanisms with joint clearance and fragmentation behavior using the theory of vector form intrinsic finite element(VFIFE). VFIFE has the advantage of handling the process of movement associated with large deformation, such as rupture, penetration, impact or non-linear movement. Mechanisms with joint clearance may possess shorten life due to wear and impact to the mechanism that are caused by the joint clearance. Therefore, by using VFIFE associated with contact models for the joint clearance, motions of mechanisms are investigated and simulated. In addition, the fragmentation behavior for mechanisms that are subject to internal stress/strain which are caused by joint clearance are also discussed and simulated via VFIFE. It is shown that the results of the study are rational and feasible.
