| Summary: | 26.7 'C, 40 'C, and 70 'C on 1.27 cm , 0.953 cm, and 0.635 cm and was sensitive to changes in material processing. A plane crack length within fifteen percent error. Correlation with determined indirectly from changes in the compliance of the elevated temperatures. The new methods predicted the actual evaluate the new test and analysis methods. Static loading factor in long-term service of plastic pipe or other in a plane strain stress state. material. The crack length as a function of time was method was developed to study slow crack growth in of deeply notched three-point bend specimens was conducted at polyethylene. Two high density polyethylenes were used to Slow crack growth in polyethylene is often the limiting specimen coupled with a fracture mechanics analysis. The new strain stress state was not achieved in any thickness at the strain stress state was obtained in all three thicknesses of structural applications. A new test method and analysis test method was able to distinguish between the two materials the lower toughness material at 26.7 'C. However, a plane theoretical models was possible only when the specimens were |
