Research of stress field intensity model on the fatigue strength prediction for welded steel structures 焊接钢结构疲劳强度预测的应力场强模型研究
Area method and stress field intensity approach to estimate the fatigue strength of welded steel structures are presented in the paper 本文分别建立了焊接钢结构疲劳强度预测的面积法和应力场强法的理论。
The effectiveness of predicting model is proved by means of comparison between predictions and experiments for a few types of welded steel structures 通过对几类典型焊接钢结构疲劳强度的理论预测与疲劳试验结果的比较,验证了理论模型的正确性。
One point method , mean square curve method and the maximum likelihood principle to predict p - s - n curve for welded steel structures for arbitary survival rate are presented 本文建立了任意存活率下焊接钢结构p - s - n曲线预测的一点法,均方差曲线法极大似然法。
