natural stress
3.AIM: In the condition of vertical dead load, modeling natural teeth compares with von-mises stress of post inlay of nichrome and rhotanium, three-dimension finite element method is applied to analyze the von-mises stress distribution of post inlay restoration for residual crown of lowers jaw molar.
6.In exploiting offshore oil and natural gas, China follows the policy of placing equal stress on oil and gas, with the balance inclined slightly toward gas, combining domestic exploration and exploitation with cooperation with foreign companies, and integrating upstream and downstream. As a result, great progress has been made.
7.This paper presents the analysis of natural vibration of cylindrical mast under the assumptions of membrance stress state and unvariability of the transverse section shape by using synthetic discrete method Some numerical results calculated by micro computer are given and compared with the solutions of the SAP-5 program.
10.This article analyses the reinforcement mechanism of pile-net composite foundation mainly, combining natural equilibrium arch theory and reinforced cushion tension membrane theory to deduce the calculation formula of the stress ratio of pile-soil in the pile-net composite foundation under embankment.
