Failure of a PVC Water-Filter Housing

Abstract
An injection-molded PVC water-filter housing fractured in service. 75x views and visual inspection supported the conclusion that failure occurred due to fatigue crack propagation, as indicated by the presence of discontinuous crack-growth bands and their evolution. However, an initial fissure was believed to have started first due to residual stresses developed during injection molding. No recommendations were made.
