Theoretical stress formula
Webb17 okt. 2024 · The formula for calculating the flexural stress: σ = F / bd Where: σ = Flexural Stress F = Axial Load at Fracture Point b = Width of Polymer d = Thickness of Material Let’s solve an example; Find the flexural stress when the axial load at fracture point is 11, the width of polymer is 17 and the thickness of material is 27. This implies that; WebbStresses formed by the contact of two radii can cause extremely high surface stresses. The application of Hertzian Contact stress equations can estimate maximum stresses produced. These stresses can then be analyzed in context of the application. In many cases, the resultant stresses are not of design significance, but in some cases failure …
