Strain energy for axially loaded bar
Webδ = P L A E = σ L E. To use this formula, the load must be axial, the bar must have a uniform cross-sectional area, and the stress must not exceed the proportional limit. If however, the cross-sectional area is not uniform, the axial deformation can be determined by considering a differential length and applying integration. δ = P E ∫ 0 L ...

WebStep 2: Write the expression for the PE of the system. Step 3: Find the minimizers of the PE of the system.) Employ the RR method to compute an approximate solution for the displacement in a beam under axial load. Differentiate between the requirement for an approximate solution and an exact solution. The Rayleigh Ritz method is a classical ... WebStrain Energy is defined as the internal work done to deform a body by the action of externally applied forces. Let’s say we have an axially loaded bar on which load is applied gradually which increases from 0 to P and due to this load the length of the bar increases by ΔL. The external work done by the applied load will be given as ...
