Included are burst loss probability, delay penalty and correlation benefit.

Tensile,compression,torsion,and fine blanking tests of 45 steel were performed, and the stress triaxiality and ductile damage of each test are analyzed with FEM.

Based on the continuum damage mechanics(CDM),a unified model of ductile damage evolution is proposed.

In this paper, the plastic strain energy that a material absorbs in static loading is used to define the ductile damage variable of the material, which could overcome the limitations of the other definitions and describe all damage changes in the ductile damaging process.

In the authors’ previous work, a step-by-step approximation approach was used to obtain the parameters in the above model, and an index named "relative time up to accumulate half damage" was suggested to evaluate the dynamic damage delay of concrete.

To ensure that the concrete can easily flow past the bored pile reinforcement cages throughout the whole process while the piles are being concreted, the delay loss test as long as 10 hours was made under minimum slump condition allowed in the Technical Specification of Paksey Bridge.

Objective To observe the relationship between the expression of GFAP and iNOS the post-traumatic intervals after experimental cerebral contusion,in order to attempt to find out a method of timing wound age of brain contusion in the forensic prediction of injury time.
