The tensile experiments were carried out under different conditions of pulse current on pure titanium. The influence of pulse current density on the the actual stress strain curve, elongation and the tensile strength were also analyzed. The experimental results show that pulse current could change material...

The fatigue properties and S-N curves of the 3mm thickness SUS301L-MT and 5mm thickness SUS304 stainless steel sheet lap fillet welded joints made by plasma arc welding, plasma-MIG hybrid welding as well as resistance spot welding are investigated respectively based on the results of fatigue tests. The...

The effect of adhesive thickness on the vibration features of the steel disc was investigated by the modal analysis, buckling analysis and static analysis based on the practical application. The results from the elasto-plastic finite element analysis show that the natural frequency of the structure is...

The numerical analysis of the inner step length on the stress distribution in weld-bonded single aluminum lap joint was investigated using elasto-plastic finite element method (FEM). The results from the numerical simulation show that the peak stress along the bondline peak stress at the end of lap zone...

The effect of the nugget position on the stress distribution in aluminum single-lap weld-bonded joint was investigated using elasto-plastic finite element method (FEM). The results from the numerical analysis show that all the peak stresses of stress components Sx, Sy, Sxy and von Mises equivalent stress...

The effect of the adhesives modulus from 0.05 GPa to 6 GPa on the stress distribution in weld-bonded single lap Dual Phase 600 steel joint was investigated using elastic finite element method (FEM). The results from the numerical simulation show that all the peak values of the stresses along the mid-bondline...

The die optimization design is an effective way of overcoming the extrusion problems of plastic tube. Due to the obvious influence of the rheological properties of melt on the extrusion shape of the plastic tube, the reasonable cross-section shape of the die is one of most important factors in the die...

Grinding force has important effects on the forming and quality of the hardened layer. The grind-hardening test of 42CrMo steel was carried out on a forming grinding machine. The results show the chief influence factor on the tangential and normal grinding force is the grinding depth, the grinding speed...

The effect of the nugget size from 2 mm to 8 mm in the lap zone of the adherend on the stress distribution in weld-bonded single lap DP 600 steel joint was investigated using elastic finite element method (FEM). The results from the numerical simulation show that the value of the peak stress along the...

Grind-hardening is not only a complex process coupling mechanical, dynamical and thermal effects, but a process containing distinct changes of microstructure and performances in the surface layer of the grinded workpiece. Based on the software Deform-2D, this paper simulated the distribution and variation...
