摘要
介绍了作者最新提出的防止塑性垮塌的新准则,并与ASMEⅧ-2规范和EN 13445标准中的相应准则进行比较。新准则吸收了ASME和EN标准的优点,并能较好地处理屈强比较低或几何强化较明显的情况。
A new protection criterion against plastic collapse presented by authors is introduced in this pa- per. Comparison of this criterion with corresponding one of the ASME Ⅷ - 2 code and the EN 13445 standard is given. The new criterion is not only able to absorb the advantages of the ASME code and EN standard but also able to deal well with the conditions of low yield-strength ratio materials and remarkably geometrical strengthening effects.
