Numcrical calculations show that the impactcompression effect of spring is important for dynamic strain of the fixed end.
分析结果表明，考虑弹簧冲击压缩效应与否，对弹簧固定端动态应变历程有很大影响。

Conclusion Under impactcompression the radius gets fractured easily at both ends, especially at distance section, and the fracture is related to time.
结论在冲击压缩力下，桡骨的两端，尤其是远端容易骨折，并与时间有关。

When impactcompression test is exerted, the pulse shaper has been used to regulate the incidence wave, so that the stress gradient will not be significantly high and the results is acceptable.
