Consideration of mechanical fracture for plastics pressure pipe as viewed from application;

To predict the cracking of rice grains during drying, transporting and subsequent storage, information must be available about modulus of elasticity, such as failure force, failure stress and failure energy.

The failure mechanism of steel fiber-reinforced concrete bridge pavement in concrete highway bridges was studied by utilizing the model in conjunction with the linear elastic fracture mechanics,and the influence of temperature variation on the failure stress of pavement layer or failure moment was considered.

This paper uses circular disk models in experiments to measure failure stresses around the hole,because its axial symmetry can decrease the material discrete influence.
