Fatigue Design of Various Type Spot Welded Lap Joints Using the Maximum Stress
Recently, a new issue in designing spot welded structures such as automobile and train car bodies is to predict an economical fatigue design criterion. One of the most typical and traditional methods is to use a ΔP--N^sub f^ curve. However, since the fatigue data on the ΔP--N^sub f^ curve vary accor...

| description | Recently, a new issue in designing spot welded structures such as automobile and train car bodies is to predict an economical fatigue design criterion. One of the most typical and traditional methods is to use a ΔP--N^sub f^ curve. However, since the fatigue data on the ΔP--N^sub f^ curve vary according to the welding conditions, materials, geometry of joint and fatigue loading conditions, it is necessary to perform the additional fatigue tests for determining a new fatigue design criterion of spot-welded lap joint having specific dimension and geometry. In this study, the stress distributions around spot welds of various spot welded lap joints such as in-plane bending type (IB type), tension shear type (TS type) and cross tension type (CT type) were numerically analyzed. Using these results, the ΔP--N^sub f^ curves previously obtained from the fatigue tests for each type were rearranged into the Δσ -N ^sub f^ relations with the maximum stresses at the nugget edge of the spot weld.[PUBLICATION ABSTRACT] |
