Abstract :

Snap fits are the simplest, quickest & most cost effective method of assembling two parts. Basically, a molded undercut on one part engages a mating lip on the other. This method of assembly is uniquely suited to thermoplastic materials due to flexibility, high elongation and ability to be molded into complex shapes. In this research paper a 2D model of snap lock is generated in ANSYS software to study the non linear contact analysis between the mating lips. Result generated by the FEA software ANSYS, allows to evaluate and optimize the snap joint prior to committing costly prototypes and tooling.
