- a. Discuss the engineering applications of thermal stresses.A 30 ?? square plate is subjected to uniform pressure as shown in Figure.1. The 2D loading stressesare described. If the modulus of elasticity is 200 ??? and the lateral constant (Poisson's ratio ? = 0.3). Estimatethe change in length in the vertical, horizontal and diagonal sides as well as determine the volumetric strain.Illustrate the effect of two-dimensionalstrain by constructing appropriate sketches (before and after deformation).Repeat the analysis for lower value of pressure and higher value in the range of [20 -100 MPa] and comment onthe overall results.For a piece of copper alloy, a standard stress test was applied to it, the following data was collected, from which a stress-strain diagram must be generated, where as data it is known that the initial diameter of the element is 0.505in. The analysis must include the following: 1.Modulus of Elasticity and modulus of resilience. 2.Percentage of elongation. 3.Percentage of area reduction. 4.Real and engineering stress at fracture. It is known that after the specimen fractures, its dimensions in terms of length and diameter are 3.014 and 0.374in, respectively.

You realize with horror, in the middle of your presentation, that you forgot to label your calculated curves (below). Which curve is which? Pick the best answer A: "Plot 1 is HYPERFILL® and Plot 2 is p-GMAW. Since HYPERFILL® has the higher heat input, it cools more slowly." B: "Plot 2 is HYPERFILL® and Plot 1 is p-GMAW. Since HYPERFILL® has the faster travel speed of the two processes, it cools faster." C: "Plot 1 is p-GMAW and Plot 2 is HYPERFILL®. Since p-GMAW has the slower travel speed, it cools more slowly."

- A 2-cm-long through thickness crack is discovered in a steel plate. If the plate experiences a stress of 50 MPa that is repeated at a frequency of 30 cpm, how long would it take to grow a crack, corresponding to the design limit where Klimit = KIC/3? Assume that KIC = 90 MPa √m and the material possesses a growth rate relation where da/dN = 4 x 10-37 ΔK4, with da/dN and ΔK being given in units of m/cycle and Pa √m , respectivelyA 3-cm-diameter penny-shaped slag inclusion is foundon the fracture surface of a very large component made of steelalloyed with Ni, Mo, and V. Could this defect have beenresponsible for the fracture if the stress acting on the component was 350MPa? The only material data available areCharpy results in the transition temperature regime whereimpact energy values of 7–10 ft-lb were reported. Be careful ofunits when you consult the KIC–CVN conversions.Analyse effects of cold work and Annealing in term of change in microstructure and mechanical properties.
