The influences of cement strength grade and fiber addition on the critical tensile strain and ultimate tensile strain of the concrete from 1 d to 180 d were investigated in flexural tests.

Effect of the initial strains on the quenching residual stress during the quenching process;

This method is not only convenient to consider tubular initial stress and temperature initial strain,but also is of self-superiority,computing result for calculated examples indicate that this method is feasible.

The principle of initial strain method using degree of creep is represented for creep increment analysis considering construction proce.

The failure mode of thin-walled RC box-beams with externally bound carbon fiber reinforcing plastics for bending reinforcement was discussed on the basis of the stress-strain relationship of a variety of materials for concrete components,principle of consistent deformation,and consideration of initial strain of the beam.

The tendon element with initial strain was used to analyze prestressed LICS and included in structure model all the time.

In this paper, elasto-viscoelasto-viscoplastic model is adopted and FEM formula of initial strain method is presented to analyze the stability of the slope in the Xiaolangdi project.

The experiments showed that the tensile fracture strain of such PMMA specimens was nearly ten times of that un-precompressed.

A study is made to determine how the stress triaxiality, temperature and strain rate could influence the fracture strain of SiC particulate reinforced metal matrix composites (PRMMCs).
