Stress Concentration Factors

Based on the grouping method and lifting and lowering method, the weld joints of TCS stainless steel such as butt joint and corner joint were experimentally examined to clarify their fatigue properties in axial loading. The probabilistic S-N curves were established from the viewpoint of the survival probability and confidence level, and the stress concentration factors were evaluated by using finite element model. As a result, corresponding to fatigue life of N=2×106, the mean values of fatigue limit for corner joint and butt joint are evaluated to be 162.7MPa and 173.7MPa, respectively. The stress concentration factors for butt joint and corner joint are evaluated to be 1.55 and 2.22, respectively.

Stress Concentration Factors

The paper deals with the problem of stress concentration at the weld toe of a plate T-joint subjected to axial, bending, and shearing loading modes. Theoretical stress concentration factors were obtained from numerical simulations using the finite element method for several thousand geometrical cases, where five of the most important geometrical parameters of the joint were considered to be independent variables. For each loading mode—axial, bending, and shearing—highly accurate closed form parametric expression has been derived with a maximum percentage error lower than 2% with respect to the numerical values. Validity of each approximating formula covers the range of dimensional proportions of welded plate T-joints used in engineering applications. Two limiting cases are also included in the solutions—when the weld toe radius tends to zero and the main plate thickness becomes infinite.

Stress Concentration Factors

A review of the Stress Concentration Factors (SCFs) obtained from normal and oblique holes in thick flat plates loaded in uniaxial tension has been conducted. The review focuses on values from the plate surface and discusses the ramifications of making a plane stress assumption.
