What is Stress Concentration - Definition,Causes,effects

Apr 06,2017 Effect of mechanical and fractographic properties on hole#0183;Stress concentration is the accumulation of stress in a body due to sudden change in its geometry.When there is a sudden change in the geometry of the body due to cracks,sharp corners,holes and decrease in the cross section area,then there is an increase in the localised stress near these cracks,sharp corners,holes,and decreased cross section area.The effects of stitch orientation on the tensile and open Mar 01,2012 Effect of mechanical and fractographic properties on hole#0183;Highlights Effects of stitch orientation on in-plane properties of plain weave is studied.In-plane properties include tensile and open hole tension properties.Stitch orientation greatly affects the strength of plain weave.Stitch orientation determines the direction of crack progression.Stitch orientation does not affect the stress distribution around the hole.The effect of mechanical properties on hole flangeability Effect of mechanical and fractographic properties on hole#0183;Effect of Structural Changes on Microstructure,Mechanical Properties and Fractographical Analysis of Binary Al-12si Base Alloy Devappa 1,T.M.Chandrashekharaiah 2,D.N.Roopa 3,Somashekar Hiremath 4 1 Assistant Professor,Department of Mechanical Engineering,JSS Academy of Technical Education,Bengaluru,Karnataka,India.

Strength degradation and fractographic analysis of carbon

Fractographic analysis figures out the failure mechanism of tested specimens by correlating their mechanical properties.SEM micrographs and data analysis reveal that axial splits and local delamination effectively blunt the stress concentration around the hole resulting in higher OHT strength and less notch sensitiveness towards tensile strength.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextEffect of Free-Volume Hole Fraction on Dynamic Mechanical Effect of Free-Volume Hole Fraction on Dynamic Mechanical Properties of Epoxy Resins Investigated by Pressure-Volume-Temperature Technique J Phys Chem B .2020 Mar 5;124(9):1824-1832.doi 10.1021/acs.jpcb.9b10978.Some results are removed in response to a notice of local law requirement.For more information,please see here.
