Based on the perzyna's elasticvisco-plastic model, the hardening effects of strain rate have been studied in this paper.The dynamic loading conditions are given,assuming that the loading surfaces will be not only isot-ropic and uniform expasion or contraction but also translational motion because of strain rate in the space of deviatoric stresses. Using the model and Laplacian transform,the closed solutions of thick walled cylinder subjected to internal pressure have been obtained.

本文在Perzyna弹粘塑性模型的基础上,研究了应变率的硬化效应。假设应变率不仅使加载面作各向同性的均匀胀缩,而且还使它在偏应力空间产生一个移动量,从而得到了动力加载条件,本文用此模型和Laplace变换求得了受内压作用下厚壁圆筒的封闭解。

This paper introduces a series of dynamic model experiment of R/C column executed on large shacking table and anew concept about failure by the authors developed from the test. Under the function of dynamic loading, the stress-strain relationship is basically the same with static result before the column cracks. Under cyclic reversed loading, when the tensile stress of a section reaches or beyonds the limitation of concrete, a sudden-crack-change may happen. Those columns finally failed in inclined mode also undergo a consequent sudden change along the inclined crack.

本文介绍了作者近年来在大型振动台上进行的钢筋混凝土柱模型的动力试验,以及作者根据试验所提出的新的破坏概念。在周期性动力荷载作用下,构件在开裂前,其应力一应变关系与静力基本一致。当截面混凝土的拉应力达到或超过抗拉极限值时,在反复力作用下,裂缝很快贯通,刚度突然降低,原由混凝土承受的拉力突然传递给纵向受力钢筋,形成开裂突变。这种现象是既往静力或拟动力加载所没有的。因此,这种突变改变了传统的P-△关系。影响开裂突变的因素包括主筋配筋率、钢筋种类、加载频率及模型自身的振动特性。试验表明,多数构件在经历一系列振动作用后会产生上述突变,但最终以斜截面破坏的柱子,还会沿斜裂缝产生第二次开裂突变。文中叙述了上述特性,展示了突变后强度与变形的关系和截面配筋条件对两次突变的影响。这一成果有力地动摇了延性抗震概念,并对新的动力抗震设计方法提供了试验依据。

本文报道了干、湿两种牛密质骨在动力加载情况下SGP和应变、应变串间相互关系的实验研究。实验中采用了传统的SHPB技术,发现湿骨中SGP有明显的滞后现象,实验支持在湿骨中把流动势看作SGP的主要根源的观点。
