Experimental Designs for Estimating the Correlation Between Two Destructively Tested Variables
研究了在假设联合正态分布下，通过先对样本进行验证加载（如弯曲）再加载至破坏（如拉伸）的实验设计，以估计两个强度变量之间的相关系数，并确定了最优验证载荷。
Abstract A specimen can have two or more important strength properties. These could be its bending strength and tensile strength. Assuming joint normality, we study experimental designs for estimating the correlation coefficient. The specimen is proof loaded—say, in bending. If it does not fail, it is loaded in tension to failure. Optimal proof loads are determined. Large sample properties of the maximum likelihood estimator are also given.
