机械强度可靠性计算的一种新的迭代方法

A New Iterative Method for Calculating the Mechanical Strength Reliability

提出了一种计算机械强度可靠性指标的迭代方法，这种方法克服了一次二阶矩方法的缺点，对于非线性极限状态函数非常有效．实例计算表明：这种方法具有很好的收敛性和很高的计算精度．

A new iterative method is proposed for calculation the mechanical strengh reliability index,and the shortcoming of the first order second moment method has been overcome by this method,which is especially valid for nonlinear function in limiting state.The numerical results show the better convergence and higher precision.
