Bending Moment And Shear Force Diagrams – What Are They And How Can They Help Validate Your FEA?
When a beam is loaded, the effect is not limited to the visible external forces. Internally, the structure develops reaction forces, shear forces, and bending moments that vary continuously along its length. If an engineer wants to know where stresses will be highest, where yielding may begin, or whether an FEA result is physically reasonable,
