Stress concentration beam with hole
WebJan 22, 2024 · The height of the cross section is 100 mm, so if the standard form of Saint-Venant’s principle is applicable, then the stresses should be small at a distance of approximately 100 mm from the end section. Equivalent stress in the beam. The red contour indicates where the stress is less than 5% of the peak applied stress. WebQuestion: Engineering texts and handbooks often include tables of stress concentration factors. Use one of these tables to determine the theoretical stress concentration for a ¼” diameter hole drilled through the center of a ¼” x 1” rectangular beam in simple bending. Report the found Kt value as well as the source you found it.

With equal, maximum stress mag-nitudes the fringes are counted at one edge where the stress is calculated from theory. Normally ... WebNov 30, 2024 · 1. In your example (a hole in a bar loaded axially), the hole stretches. This causes the stress around the hole to vary. The locations where the hole changes curvature the most is where the stress is a maximum. From this, the stress concentration can be calculated: k=max stress/average stress. Here is an image from a finite element analysis ...
