Strength Design

Study on Strength design of steel components including residual stress. First, sample with residual stress of shot peening were detected, material properties change with residual stress was analyzed. And problems in the strength design were discussed. On this basis, design criteria for design of static strength and fatigue strength under plane stress state were derivated, the design criteria formula of the unification form is obtained. Finally, examples illustrate the reasonableness of the conclusions and deriving formulas.

An approach to obtain analytical closed-form expressions for the macroscopic ‘buckling strength’ of various two-dimensional cellular structures is presented. The method is based on classical beam-column end-moment behaviour expressed in a matrix form. It is applied to sample honeycombs with square, triangular and hexagonal unit cells to determine their buckling strength under a general macroscopic in-plane stress state. The results were verified using finite-element Eigenvalue analysis.
