Abstract. Clinching is a versatile mechanical joining method for assembling different sheet metal materials without auxiliary elements in short process times. The joint strength, however, solely relies on the material condition and its targeted interlock formation. Therefore, accurate models are necessary incorporating all relevant phenomena to reliably predict behaviour. We extend finite elast...

Abstract Knowing that the end effects arising from torsional loads will disturb stress distribution in a torque tube, this paper develops means of blocking disturbances where load is applied, such distributions Saint Venant torsion can be maintained. The disturbance barrier (SDB) as an effect shielding considered installed on circular toque tube whose material property with cylindrical orthotro...

We consider elastic waves in materials with cylindrical orthotropy, this being a plausible model for wood. For time-harmonic motions, the problem is reduced to some coupled ordinary differential equations. Previously, these have been solved using the method of Frobenius (power-series expansions). We use Neumann series (expansions in Bessel functions of various orders), motivated by the known cl...

In this research paper, we present a novel frame work for handling $m$-polar information by combining the theory of $m-$polar fuzzy  sets with graphs. We introduce certain types of edge regular $m-$polar fuzzy graphs and edge irregular $m-$polar fuzzy graphs. We describe some useful properties of edge regular, strongly edge irregular and strongly edge totally irregular $m-$polar fuzzy graphs. W...

Stress Intensity Factors (SIFs) for cracks emanating from circular holes in two-dimensional orthotropic bodies were numerically computed taking into account the effect of geometry and orthotropy. A semi-analytical expression correction factor was found fitting numerical data. Finally, it demonstrated how same can be used to calculate SIF elliptical once appropriate changes variables are made. •...
