Our objectives in carrying out this investigation were to evaluate the effects of specimen geometry on the elasticity and strength characteristics of the involved PA12 material. One-way ANOVA analysis, Tukey's HSD, and Games-Howell tests were considered to compare the mean ...
1. It shows that the dimension of gage (the central portion with equal section)is critical for the stress distribution in the dog-bone-shaped specimen. 结果表明:狗骨形试样中,中间等截面段尺寸对试样中应力的大小、分布影响很大。2) dog bone shape 狗骨形...
This paper analyzed the distribution of stress within clear-wood dog-bone specimen using an analytical stress-recovery and a refined 2D FE analysis. Both the methods agree indicating the presence of non-negligible transversal and shear stresses in the transition zone between necking and gauge regions...

Dog-bonePrestressFinite elementIn the present work, simple tensile test of shape memory alloys (SMAs) is studied by considering stress concentration caused by the grippers. In order to simulate SMA behaviors, finite element method is employed to obtain prestress distribution along the specimen due ...
To eliminate the holding and gluing problems making the direct tensile strength test hard to be applied, a new method of testing rock material specimens prepared using lathe machine to make the dog bone shape is assessed whether it could be applied to determine accurate direct tensile strength ...
