ENGIN 45 Study Guide - Midterm Guide: Stress Concentration, Structure Factor, Tetragonal Crystal System
Document Summary
+2 points for correct answers, -1 for incorrect answers, 0 for blanks (a) elastic deformation is (f) poisson"s ratio describes. Both of the above behaviors (b) hardness is. Resistance to elastic deformation (g) cyclic loading at low stress can. Be a combination of both effects (c) the slope of the linear portion of a (h) a transition from ductile to brittle failure stress-strain curve defines. The proportionality limit can occur in plain carbon steels. At low carbon concentrations (d) engineering stress is (i) creep deformation. Equal to true stress at high strain. Depends upon melting point (e) on stress-strain plots below, yield stress (j) stress concentration in the samples. Is higher for higher values of strain below with through holes. Is identical for (i) and (ii) (i) (ii) page 1 of 5. Instructions: mark the ballot box corresponding to the best answer.
