The fracture characteristics of fiber reinforced materials subjected to off-axis tensile load are observed to indicate that there is a certain angle in which direction the off-axis tensile fracture approximates well to pure shear fracture. A method of optimal angle for off-axis tensile test is then provided for determination of the shear stress-strain characterization of composites. Other testing methods, for example, [±45°]s off-axis tensile test suggested by Rosen or/and 10°off-axis tensile...

The fracture characteristics of fiber reinforced materials subjected to off-axis tensile load are observed to indicate that there is a certain angle in which direction the off-axis tensile fracture approximates well to pure shear fracture. A method of optimal angle for off-axis tensile test is then provided for determination of the shear stress-strain characterization of composites. Other testing methods, for example, [±45°]s off-axis tensile test suggested by Rosen or/and 10°off-axis tensile test suggested by Daniel and Chamis can be regarded as the specific case of,this method. The method provided in this paper, therefore, is seemed to be more perfect and has more general significance. Tests with various off-axis angles have been performed and the results are in good agreement with those predicted theoretically. Thus, the validity of this method is verified.

本文通过对偏轴拉伸下破坏特点的分析,说明在特定最优偏轴角下的偏轴拉伸破坏十分接近于纯剪破坏,提出了测定完整(ι_(12)~γ_(12))曲线的最优偏轴角拉伸试验方法。它概括了Chamis和Sinclair~([1]-[3]的10°偏轴和Rosen~[4]的45°偏轴拉伸方法,使偏轴拉伸法更完善并具有更普遍的意义。通过对1:1玻璃布/环氧、4:1玻璃布/环氧、7:1玻璃布/环氧三种玻璃钢的偏轴拉伸试验,得到与理论分析相当一致的结果,验证了这一方法的可靠性。

On basis of studying the superplastic deformation behavior and the microstructural changes of the Zn-4%Al alloy the nucleation and propagation of the cavities and their influence on the ductility and fracture characteristics were exammed.Experimental results indicate that cavities are formed during superplastic deformation due to the inconsistency of grain boundary sliding.The cavities form essentially on triple points of grains and affect the deformation processes in two aspects.The first of them is to consist the deformation and the second is to result in the fracture of the specimen by cavity coalescence.The propagation of the cavities can be controlled and thus the ductility of the alloy can be increased by suitably controlling the deformation conditions.

本文在研究Zn—4%Al合金超塑性变形行为和显微组织变化的基础上对孔洞的生核和扩展、孔洞与延伸率的关系、孔调与断裂的关系等进行了观察和探讨。实验结果表明,孔洞是由于超塑性拉伸变形中品界滑动不协调而引起的。孔洞主要形成在三角晶界上,它对超塑变形有两个作用,其一是协调变形。其二是孔洞的相互连接导致试样断裂。适当地控制变形条件,可抑制孔洞的扩展,从而能提高合金的延伸率。
