Stress concentrations in a plate with two unequal circular holes

In solid mechanics, a stress concentration (also called a stress raiser or a stress riser) is a location in an object where the stress is significantly greater than the surrounding region. Stress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets. Stress concentrations may also occur from accidental damage such … WebThis tab defines the stress concentration factor for a bar with a rectangular cross section … WebStress Concentration Near an Elliptical Hole • In 1913 Charles Inglis (a British mathematician) published a solution for the elastic stresses near an elliptical hole in an isotropic infinitely large thin plate (the Inglis solution is discussed in Sec 4.2) • In this case the stress concentration depends on both the aspect ratio of github set up public key

WebDec 31, 2024 · The stress concentration factor at a hole is a dimensionless constant used to quantify the increase in internal stresses that occur in a loaded structural member with a circular-shaped opening. This increase is typically observed near the hole and can be significantly higher than the average stress across the object’s cross-section.
