Fracture is a type of material failure. Of the following which is another type of material failure? - Permanent deformation. Which of the following statements best differentiates between a defect and a discontinuity? - Discontinuities can propagate and become defects. Nondestructive testing is often differentiated from other measurements or inspection techniques in that: - NDT involves indirect tests related to some other quality or characteristic of material. What are the functions of ...

EPRI EF Nuclear Power Plant Materials Certification Latest Update Graded A+ Brittleness The opposite of ductility. Brittle metals exhibit a small percentage of elongation under stress before failure. Cold Shut A defect produced during casting, causing an area in the metal where two portions of the metal in either a molten or plastic condition have come together but have failed to unite, fuse, or blend into a solid mass. Conductivity The property of conducting heat or electric current. Crack l...

NASM Stretching and Flexibility Coach FINAL EXAM 1 TEST CORRECTLY ANSWERED Stretching and Flexibility Stress and Strain Stress: defined as the amount of tension/load placed on tissues, given in units of force/area. (pounds/square inch or Newtons/square cm) 3 types are tension, compression and shear stress. Strain (deformation): the proportional degree of elongation of tissue that occurs during the stress. Affected by the rate of the stress. (fast/slow) Recovery: the ability ...

The compression of soil layers as a result of foundation or other loadings is caused by Correct Answer-(a) deformation of soil particles. (b) relocation of soil particles. (c) expulsion of water and air from the void spaces. The elastic settlement of the ground is caused by the deformation of soil Correct Answer-(a) without a change in its water content. When a saturated soil layer is subjected to a stress increase, the porewater pressure Correct Answer-(b) increases. The drainage c...
