Find and read the standard on Test Method for Linear-Elastic Plane-Strain Fracture Toughness K Ic of Metallic Materials (E- 399). Problem 1 Explain, as quantitative as possible (but preferably brief), the difference between plane stress and plane strain deformation? Why is the fracture toughness of a metallic material invariably lower in plane strain? Problem 2 You are the metallurgist for a design group which is working on cars for the proposed Maglev (magnetic levitation) high-speed train route between Pittsburgh and Philadelphia. The structural engineer for the project asks you to help select a material for the car underframe. She has several candidate materials in mind, all of which have adequate yield strength, and which have varying densities (reduced weight of the cars...
