EAS 209-Spring 2011 Instructors: Christine Human 1/18/2011 1 05-Axial Deformation Lecture 5 Deformations of Members Under Axial Loading Last lecture we saw that provided a material remains in the linear elastic region, stress is proportional to strain E Also, since σ =P/A and ε = δ /L we can rewrite the above equation to solve for the deformation: AE PL where P is the centric axial load L is the length of the member A is the cross-sectional area E is the elastic modulus of the material Today’s Objective: Calculate the deformation of axially loaded members Today’s Homework: EAS 209-Spring 2011 Instructors: Christine Human 1/18/2011 2 05-Axial Deformation Analogy with Spring Stiffness and flexibility of a bar are defined in the same way as for a spring Spring Bar Flexibility, f Stiffness, k fP f -flexibility k P k -stiffness AE L f L AE f k 1 Unless specified, prismatic bars are assumed to have the same E (and hence stiffness) in compression and tension.
