Thermal Residual Stresses in Aligned Short Fiber Reinforced Metal Matrix Composites

单向短纤维复合材料中热残余应力研究

Using the concept of plastic hinge, the tangent stiffness matrix of spatial beam element is formed. At the same time the effect of geometry nonlinear property, residual stress and end restraint are considered.

引入塑性铰的概念，建立了空间梁单元弹塑性刚度矩阵，同时考虑几何非线性、残余应力、端部约束等的影响，给出了一套钢结构复杂体系的有限元计算方法。

Influence of residual thermal strain on tension and compression behaviors of metal matrix composites

热残余应变对金属基复合材料拉、压性能的影响

Based on statistical power of detecting QTL, the model with GM2 for the mean vector and "Damped" exponential model for residual covariance matrix was determined as optimal one and two QTL were detected in linkage group 3, with greater statistical power than other combinations.

其结果GM2和衰减指数模型组合被确定为用来检测水稻第3个连锁群控制叶龄动态变化QTL的优化模型。
