Crack Initiation and Propagation FEM Grain Boundary Slip Microscopy Heterogeneity Molecular Dynamics
This study proposes numerical analysis model considering grain boundary slip and microscopic h eterogeneity in order to estimate stress distribution which effect crack initiation and propaga tion. The FEM-MD combined method for considering grain boundary slip is discussed. The estimat ion of mechanical properties for taking account of microscopic heterogeneity is also discussed....

Clamp Piling joint Residual stress Thin plate Welding deformation
This study is considering the effect of clamp conditions on welding deformation and residual st ress distribution. Welding deformation and residual stress becomes initial imperfections, and i t causes structures weak so it must be controled. The result of numerical analysis shows that an appropriate conditions should be chosen by considering welding distortion and residual stress....

Fatigue Strength Low temperature transformation welding wire Residual stress Welding deformation
This study shows the effect of the low transformation temperature welding material on residual stress listribution and welding deformation. The expansion due to the transformation fr om austenite to martensite nduces the compressive residual stress around welds. While, in the welding structures, it is important to control the welding deformation and residual stre ss so that they may cause the strength decrease. By using he low temperature transformation welding wire, it may be possible to decrease the weld...

Cutting & Welding distortion Dispersion Initial residual stress Straightening
This paper studies the effect of initial residual stress on high-precision manufacturing for infrastructure integrity technology. Welding distortion decreases the strength of welded structure. Straightening causes secondary deformation. Althogh welding distortion should be reduced, handling welding distortion is difficult. One of the reason is the dispersion o f cutting and welding distortion. In one of the contributing factor there are an influence of initial residual stress. When the equalization of init...
