This study investigated the effects of welding parameters on temperature distribution of magnesium alloy AM60B during Friction Stir Spot Welding (FSSW). The welding parameters included tool rotational velocity, plunge depth, and holding time. These parameters were selected from previous test results. The temperature distributions were measured with type-K thermocouples during FSSW with various welding parameter combinations. The measurement locations were placed along the centerline in longitudi...

Abstract This project built a two dimensional finite element (FE) model for resistance spot welding (RSW) process of Mild steel with three sheets assemblies instead of conventional two sheets stack ups on practical aspect of industry applications. The thermal-electrical coupling method was implemented to investigate transient thermal characteristics during resistance spot welding history with commercial software code, namely ANSYS. Temperature dependency electrical and thermal material propertie...

An analytical solution to calculate a fatigue damage spectrum for a linear single degree-of-freedom system is presented to assess fatigue damage severity for various vibration test specifications. This solution can be served as the fundamental to develop an accelerated vibration test specification based on the real measured customer usage data and the use of material. Fundamentals of vibration characteristics for sinusoidal and random vibrations are well described in this paper. The state-of-the...

Abstract This paper describes the fatigue characteristics of spot welds for three equal thickness sheet stack-ups of a Dual Phase (DP600) welded to itself and a Mild steel welded to itself under tensile shear loading. The experiments were designed to investigate the effects of electrode tip geometries, surface indentation levels, and base metal strengths on fatigue life of the tensile shear spot welds. The electrode tip geometries were B-nose for DP600 and Mild steel and E-nose for DP600. Surfac...

In an attempt to develop fatigue monitoring system, two improved fatigue evaluation schemes have been proposed to monitor fatigue degradation in major components and piping of the pressurized water reactor. Proposed methods are both aimed to obtain realistic fatigue usage factors for given plant transients. Developed schemes utilize plant operating signals such as coolant temperature, pressure and flow rate. Finite element method and an improved Green’s function approach were used to calculate s...

This paper describes local strain measurements of electrical resistance spot welds for three sheet stack-ups of Dual Phase (DP600) and Mild steel under quasi-static tensile loading. The experiments were designed to measure local strain distributions at the vicinity of the spot welds using a modified tensile-shear specimen geometry that allows a strain measurement system to access such area. The electrode tip type used was B-nose, and surface indentation levels were 30% and 50% of the sheet thick...

Abstract A crankshaft is often designed with a small fillet radius. The crankshaft fillet rolling process is one of the commonly adopted methods in engineering to improve fatigue life of the crankshaft. Compressive residual stresses on and below the fillet radius surface are induced through the fillet rolling operation. Consequently, fatigue life of the crankshaft is improved. An analytical technique is used to optimize the crankshaft rolling process to comply with a crankshaft design criterion ...

This paper presents a design process of an automotive bucket seat frame using a parametric modelling approach. The design process involves, first, optimising a generic seat frame using OptiStruct optimisation software. Then, a parametric model of the seat frame was developed based on the optimisation analysis results using CATIA V5. The design parameters were changed in the parametric model and numerous static tests were also performed using CATIA V5. Design of Experiment (DOE) study was then co...
