利用飞轮式Hopkinson拉杆实验技术对钨质量分数为93% 的钨合金在-50~100℃温度范围、应变率ε=102~103s-1区间的动态拉伸性态进行了测试,提供了相应的σ-ε曲线和最大拉伸失效应变,并以此为依据建立了该合金动态拉伸行为的本构关系,提出了该合金受动载发生塑性失稳以致发生拉断的判据。利用断口分形分析理论,对试件拉伸断口微观特征所作的分析和对宏观力学性态实验所作的结论给予了有力的支持。

Taking into account the effects that the components of tension stresses couple with components of torsion stresses when off-axis loads are applied to orthotropic materials, Hill s yield criterion for plastically orthotropic solids is modified by adding an invariant that is composed of the product item of quadratic components of the deviatoric stress tensor, and a new yield criterion is put forward in terms of the characteristics of the face-centered cubic (FCC) single-crystal material. The correlation of prediction and experiments is very good, and the new criterion is used to predict the yield stresses of an internal single-crystal, Nickel-based superalloy, DD3, which is more accurate than that of Hill s at 760?C. Equivalent stress and strain that adapt to the new criterion are defined. Thinking of the yield function as a plastic potential function from the associated flow rule, the elastic plastic constitutive model for the FCC single-crystal material is constructed, and the corresponding elastic plastic matrix is educed. The new yield criterion and its equivalent stress and strain will be reduced to Von Mises yield criterion and corresponding equivalent stress and strain for isotropic materials.

分析了经典塑性力学用于岩土类材料的问题,它采用了3个不符合岩土材料变形机制的假设。从固体力学原理直接导出广义塑性位势理论,将经典塑性力学改造为更一般的塑性力学——广义塑性力学。广义塑性力学采用了塑性力学中的分量理论,能反映应力路径转折的影响,并避免了采用正交流动法则所引起的过大剪胀等不合理现象,也不会产生当前非关联流动法则中任意假定塑性势面引起的误差。给出了广义塑性力学的屈服面理论、硬化定律和应力-应变关系,并建立了考虑应力主轴旋转的广义塑性位势理论。屈服条件是状态参数,也是试验参数,只能由试验给出。应用表明,广义塑性力学可作为岩土材料的建模理论,还可应用于诸如极限分析等土力学的诸多领域,具有广阔的应用前景。

针对富水全、强风化砂岩的特点,进行了该砂岩的基本物理力学性质、化学成分实验,然后通过单轴、三轴压缩实验研究了爆破扰动、含水量、试样层理对砂岩应力-应变强度特性的影响。发现砂岩遇水软化,粘聚力大幅度降低,表现出显著的各向异性;爆破扰动后,岩石试样的单轴抗压强度减低,弹模减小,泊松比增大;由于砂岩具有明显的节理性,按两种方向加载所得到的岩石试样强度明显不同;根据实验所得应力-应变曲线特点,发现用修正的Duncan-Zhang模型可以很好地描述砂岩的前应力-应变曲线。
