The result of the experiment indicated that the strength limit and elastic modulus of the material can increase after annealing treatment within the temperature range, but at the same time, the material became crisp and its plasticity declined remarkably.

Both the tensile ultimate stresses and the relations between them are examined.

In this paper,a two dimension variation method is applied to compute tensile fracture surface fractal dimensions of a grain composite material LDPE/CaCO 3,and set the relationship of tensile fracture surface fractal dimensions and tensile ultimate stress and material filler weight content percent.

Using thermal strength experiment to test and determine the pivotal parameters such as ultimate strength and thermal stress at the complicated condition of transient heating is very important for reliability estimation,life prediction of aerospace materials and security design of high-speed flight vehicle.

The failure problem of concrete bridge overlays in the system coupled by bridge deck and pavement for concrete highway bridges under vehicle loads was studied by utilizing the model in conjunction with the linear elastic fracture mechanics,and the strengths of new and original bridge overlays for an engineering example were obtained when the crack propagation occurred.
