Analysis of Stress – Strength of Materials


Real Life Application Breakage of mild steel (ductile) in tension occurs at a plane of 45° and of cast iron (brittle) in tension occurs at a plane of 0°. The answers for the above are in this chapter. Explanation Analysis of stress aims in making sure the stress on any arbitrary plane to be less than the strength of the material. It is achieved by finding out the maximum values of normal and shear stresses and changing the values of the parameters like load, area etc. which effect those values and cause failure. This analysis of stress is different in 1D, 2D & 3D
