Critical Specimen Sizes for Tensile-Shear Testing of Steel Sheets
Tensile-shear testing results are influenced not only by the quality of spot welds, but also by the dimensions of testing specimens. Experimental and numerical studies have been conducted on determining critical sizes for tensileshear testing of resistance spot welded specimens. Statistical methods have been employed, from planning stages to the analysis of results, for the purposes of getting ...
متن کاملAnalysis of the coefficient of variation in shear and tensile bond strength tests.
The coefficient of variation is a dispersion measurement that does not depend on the unit scales, thus allowing the comparison of experimental results involving different variables. Its calculation is crucial for the adhesive experiments performed in laboratories because both precision and reliability can be verified. The aim of this study was to evaluate and to suggest a classification of the ...
متن کاملUltimate Strength and Failure Mechanism of Resistance Spot Weld Subjected to Tensile, Shear, or Combined Tensile/Shear Loads
Strength tests were performed to reveal the failure mechanisms of spot weld in lap-shear and cross tension test samples. It is shown the while the lap-shear (cross tension) sample is subjected to shear (normal) load at the structural level the failure mechanism at the spot weld is tensile (shear) mode at the materials level. Based on the observed failure mechanism, stress distribution is assume...
متن کاملTensile Tests on Stainless Steels in Temperature Range
In real conditions, austenitic stainless steels solidify in non equilibrium and a two phases microstructure of austenite and ferrite is formed 1 . The aim of this work was to investigate the behaviour of both phases at tensile testing, especially to find out an eventual difference in the relaxation of the deformation energy and the effect of the two phases microstructure in workability. To achi...
متن کاملWrinkling Simulation of Membrane Structures under Tensile and Shear Loading
This paper presents a detailed Finite Element Analysis study of the formation and evolution of wrinkle pattern that observed in stretched thin membranes. The model problem is set up under the various load conditions. As a precondition for wrinkling, development of compressive stresses in the transverse direction is found to depend on both the length-to-width aspect ratio & thickness of the rect...
