摘要
本文根据弹性力学理论,通过分析边缘处应力和变形的关系,推导出边界力P_0和边界弯矩M_0的数学方程式,由此建立边界处内力的数学模型,用计算机进行边界应力的计算。
At the welded joint of a reactor joining the cylindrical body and the spherical sealing head without folded rim.no common tangent and transition arc exists. Huge boundary stress arises when an inner pressure is exerted in the vessel.The stress -strain relationship at the joint was analysed by elasticity,and mathematical expressions for calculating the boundary force and the boundary moment were derived to obtain the boundary stress.
