The elastic–plastic stresses in a rotating disc of transversely isotropic material fitted with a shaft and subjected to thermal gradient has been analyzed by using Seth’s transition theory and generalized strain measure. It has been observed that disc made of beryl and magnesium materials requires higher angular speed to yield at the inner surface in comparison to the disc made of brass material. The radial stress has a maximum at the internal surface of the disc made of beryl, magnesium and brass materials, but circumferential stress neither maximum nor minimum at this surface. With the introduction of thermal effect, the value of circumferential stress has a maximum at the external surface of the disc made of the beryl and magnesium, but the reverse results are obtained for the disc made of brass material. The combined impacts of temperature and angular speed have been displayed numerically and depicted graphically.

装有轴并受热梯度作用的横向各向同性材料转盘中的弹塑性应力

使用塞思的过渡理论和广义应变测量方法,对装有轴的横向各向同性材料旋转盘中的弹塑性应力进行了分析。已经观察到,与由黄铜材料制成的盘相比,由绿柱石和镁材料制成的盘在内表面上需要更高的角速度才能屈服。在由绿柱石,镁和黄铜材料制成的盘的内表面上,径向应力最大,而在该表面上,圆周应力既不是最大,也​​不是最小。随着热效应的引入,在由绿柱石和镁制成的盘的外表面上,周向应力的值最大,但是对于由黄铜材料制成的盘,则获得相反的结果。
