Low crushing strength selection decreased crushing strength by 35.3 load-kg per cycle for intact sections and 26.6 load-kg for rind-only sections. Intact section and rind-only weights had similar responses. Rind thickness was altered due to recurrent selection for crushing strength, but the magnitude of change was small and inconsistent.

The paper discusses the crushing behavior of glass fibre reinforced epoxy (GRE) pipes under hydrothermal ageing condition. This study determines the behavior of the GRE pipes when subjected to different ageing periods and temperatures. Hydrothermal ageing has been found to cause degradation between resin and fibre interface thus causing the reduction in the strength of composite laminates.

2010-4-11 · Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs.
