Abstract

Purpose

–

The purpose of this paper is to investigate the effects of different shape memory polymer based snap‐fits in terms of disassembly time and reusability.

Design/methodology/approach

–

In total, six different sets of snap‐fits were designed and manufactured. Each set of snap‐fits was tested ten times in a testing device for disassembly time. The stress caused by training process is simulated and analyzed.

Findings

–

One of the designs shows shortest average disassembly time, lowest standard deviation, and lowest stress. However, the overall reusability of the snap‐fits is not good enough for industrial use.

Originality/value

–

The paper tests the Veritex shape memory polymer sheets manufactured by CRG Industries LLC. The reusability has been analyzed based on the stress caused by the training process.
