Stress concentration around a hole

WebA total of 1440 elements is used for this model. Due to the singular nature resulting from the presence of the hole, stress concentration is more likely observed around the hole under tension force. To make sure the results are reliable, a finer mesh is applied near the hole. Uniform tensile stress σ 0 = 1 MPa is applied on the right side of ...

The solution can be used as ready reference to the designers for estimating the stress concentration around the rectangular hole. WebOct 3, 2024 · Many researchers have focused on stress concentration analysis in pressure vessels with hole and studied various methods of reducing these stresses (Fridman 1986; Kornecki 1966 ). Xue et al. ( 2010) presented an analytical method for nozzle placed on cylindrical vessel under internal pressure and external loads Xue et al. ( 2010 ).

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 … WebThe phenomena of stress concentration arises from the analysis of the stress field surrounding a hole, corner, or crack in a continuum. The underlying physical mechanism is really just Newtonian mechanics, subject to the assumption that the mechanical behavior of the material can be represented by a constitutive law, such as an elastic solid.

WebJun 7, 2016 · Extract An analytical solution, using complex variable methods, is given for the problem of the stress distribution due to an elliptical hole, reinforced around its boundary, in a plane sheet subjected at infinity either to an arbitrary constant stress system or to a bending type stress system. WebSection B shows the nature of stress concentration near the thru hole. It is evident that there is a disruption of stress flow lines when compared to the uniform, linear lines in section A. It is known that stress is a function of the inverse of area and the reduction of cross section at the hole increases the stress (Davies, 2010).
