نویسنده
چکیده
This study represents simulation of single spot and multi spot welded specimen by using Monte carol method i.e. Latin hypercube sampling. A three dimensional nonlinear finite element analysis of multi-spot welded lap shear specimen is performed and uncertainty in shear strength of spot weld is analyzed. Thickness and nugget radius are randomly varied within effective range and their effect on the shear Strength of multi spot welded lap specimen is analyzed. To ensure reliability of spot welds during vehicle lifetime, probability of failure of multi spot welded lap shear specimen is determined within defined ranges of input parameters. Confirmation test is conducted to validate result

Analysis of Resistance Spot Welding Process Parameters Effect on the Weld Quality of Three-steel Sheets Used in Automotive Industry: Experimental and Finite Element Simulation
In the present research, the effects of spot-welding process parameters on the nugget diameter and electrode penetration depth of spot-welded joints were investigated. To achieve this, a spot-welded joint of three-thin sheet low carbon steels (same thicknesses of 0.8 mm) was simulated as an electerical-thermal-mechanical coupling of 3D finite element model. After validating the finite element s...

Fatigue analysis and estimation of safe life of structures that are subjected to cyclic loadings, such as ships and offshore structures is one of the most important steps of structural design. Fatigue failure in the form of crack will start from details and propagate in structure. In steel structures these cracks will started from welds. Most of the methods for fatigue life assessment in welded...

The aluminum alloys of Al1050 with thickness of one millimeter and Al3105 with thickness of half millimeter were joined via ultrasonic spot welding (USW). To create a suitable welding, a vibrating horn (welding tool) fit to transducer and ultrasonic generator was designed using ANSYS software. Due to mechanical and thermal cycles during USW, both diffusion and mechanical mixing facilitated the...
