Plane Stress von Mises Screen
Calculate plane-stress von Mises equivalent stress from two entered normal stresses and in-plane shear stress.
Preliminary design support. Your inputs and results stay in this browser.
WHAT THIS SCREEN ANSWERS
Combined normal and shear stress can be compared through a plane-stress equivalent only when its assumptions fit the problem. The screen uses the entered components directly and compares the result with a user-entered limit. The simple model is a way to expose the governing question early.
Three-dimensional state, fatigue, fracture, residual stress, temperature, material condition, and geometry can govern. Confirm the actual stress state, material criterion, load cycle, geometry, and applicable design method. It needs evidence from the actual assembly or process.
Combined normal and shear stress can be compared through a plane-stress equivalent only when its assumptions fit the problem. Three-dimensional state, fatigue, fracture, residual stress, temperature, material condition, and geometry can govern. A recalculation is meaningful only when the changed assumption is visible.
The screen uses the entered components directly and compares the result with a user-entered limit. Confirm the actual stress state, material criterion, load cycle, geometry, and applicable design method. The decision remains specific to this application because combined normal and shear stress can be compared through a plane-stress equivalent only when its assumptions fit the problem. Separate a promising indication from a component selection.
