Accurate FEA of Engineering Plastics - Time-Dependent Response of Plastics

Case Study: Time-Dependent Response of Plastics

This presentation was given by Dr. Mike Bak at CAE Associates' Accurate FEA of Engineering Plastics Seminar, held on October 14, 2014 in Tarrytown, NY.

The response of a threaded plastic cap used to seal a water spigot is investigated.

  • Cap is threaded onto a pipe, compressing the washer to create a watertight seal.
  • Loading consists of the axial preload and internal water pressure.
  • Structural response over a time of 2 years is predicted.
  • Room temperature.
