设计改进分三个阶段，即局部几何性应力集中改进、提高铸造质量的纯工艺改进和锻焊组合结构抱轴箱体的设计。
Design improvement is in three stages partial, geometrical stress concentration improvement, pure casting technology improvement and a forge-weld box body design.
给出了板料弯曲的应力应变中性层和纯弯曲应变中性层的计算公式，并推出板料弯曲时的变薄系数计算公式。
The computation expression for the strain neutral layer of stress and plastic bending was introduced and so the thinning coefficient computing formula of sheet metal was deduced.
纯弹性断裂总是极少的，因之在加载应力作用下，裂纹顶端总是存在着或大或小的塑性区，存在着裂纹与位错的交互作用。
Pure elastic fracture is always rare, so th at under the action of stress, a plastic zone(large or small), and interactions between crack and dislocations always exist at the crack tip.
