The tensile strength of the composites increases with increasing the strain rate, and the failure strain decreases when the strain rate increases.

随着应变率的增加，材料的强度及弹性模量有较大程度的提高，但破坏应变有所降低。

The results of experimentation indicate that the failure load of the delaminated composite panels declines and the failure strain increases as the increasing of delaminated area.

结果表明，试验件含分层损伤面积越大，其破坏载荷越大，而对应的破坏应变越大，因此分层损伤会降低复合材料层合板的承载力和刚度。

The analysis results show that the progressive collapse resisting capacity of steel structures can be remarkably improved by increasing the failure strain of the structural material.

分析结果表明：对于钢结构，提高材料的失效应变，可以显著提高结构抵抗连续倒塌的能力。
