yield limit
1.(4) Analysis results i.ndicate:under static load, the largest stress of the dangerous cross-section of the 12. 5MN twin columns pull-down high speed forging hydraulic machine is between 60MPa and 90MPa,while under dynamic load, it is between 90MPa and ISOMPa, and they are also smaller than yield limit (270MPa)of the frame.
6.THE LIMIT ANALYSIS OF THE SPHERICAL SHALLOW SHELL OF THE RECTANGLE BASE BY TTE MISES YIELD CRITERION
10.Abstract: On the basis of investigations into the progressive yield process and the possible failure modes of RCC gravity dams,the quasi-elasticity design limit state of the ctrtical stability criterion is proposed and the real working state of the dams designed according to the ctriterion is discussed.A check formula using the material strength reducing factor as the safety index and a simplified formula similar to against sliding stability fromula are derived.Finally,the corresponding design safety factors are given by using FEM calculations with various influence parameters to be taken into account.
