V K 250 Lecture 01 1 Students need to know the following Take any simple (non-redundant) engineering structure with arbitrary combination of axial, torsional & bending loads Draw free body diagram - determine what reaction forces/moments are unknown Calculate reaction forces/moments from equilibrium Calculate forces, bending moments & torques at any section Calculate all normal and shear stresses (6 in general but, two shear stresses will generally be zero in this class ) Use Mohrs circle of stress to calculate principal normal stresses and maximum shear stresses V K 250 1. Will these stresses cause failure? Need material properties & failure criteria Excessive deformation : Time independent: elastic Time dependent: creep & viscoelasticity Strength of material exceeded Non-linear behavior: Yield Fracture: Static loading: brittle Cyclic loading: crack-based & stressed based Environmental degradation Beware of focusing on a single failure mechanism: “Implacable animosity of inanimate object” Prof. Inglis
