Elastic deformation - Study guides, Class notes & Summaries

material selection properties-what are the requirement for the most suitable structural material? Correct Answer-the structural material that combine stiffness and elasticity are considered the most suitable material. material selection properties-elasticity? Correct Answer-The ability of a material to bounce back after being disturbed - the ability of the body to deform under stress, bend, stretch and compress when the external forces are applied and return to its original shapes when the ...

CSWA-S Multiple Choice Q- Extended Edition Latest Update Already Passed What does "elastic deformation" refer to in material science? - The permanent change in shape after the load is removed. - The temporary change in shape that returns to the original form after the load is removed. - The change in color of the material when stressed. - The change in temperature of the material under load. Which type of stress analysis would you use to examine how a material behaves under cyclic ...

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...

MATSE 259 Exam 1 PSU Questions and Answers | Latest Version | 2024/2025 | Graded A+ How does strain relate to deformation in materials? Strain is the measure of deformation representing the change in length relative to the original length. What is yield strength? Yield strength is the stress at which a material begins to deform plastically. Why is Young's modulus important in materials science? Young's modulus measures a material’s stiffness, or resistance to elastic d...

MATSE 259 Exam 1 PSU With Complete Solutions Elastic Modulus (e) measure of stiffness, or a material's resistance to elastic deformation ... slope of elastic portion of stress-strain curve Crystalline Materials small group of atoms that are repeated by translation to form 3-D arrangements Antisotropic properties that vary with direction. Ex: E(edge) isn't equal to E(diagonal) Polycrystal properties that may or may not vary with direction Isotropic the grains a...

MMET 206 Test 1 Questions and Answers | Latest Update | 2024/2025 | 100% Verified What is the significance of the grain structure in metals? The grain structure in metals is significant because it affects mechanical properties such as strength, toughness, and ductility; finer grains often result in stronger materials. How do impurities affect the properties of metals? Impurities can alter the properties of metals by introducing defects in the crystal lattice, which can lead to decr...

MAE 1351 Exam 1 Latest Update | 2024/2025 | Graded A+ What does the term "mechanical advantage" mean? Mechanical advantage refers to the ratio of the output force produced by a machine to the input force applied, indicating how effectively a machine amplifies force. Define stress in materials science. Stress is defined as the internal resistance offered by a material to deformation, calculated as force per unit area, typically expressed in pascals (Pa). What is strain? ...

Lab Practical - MMET 207 - Metallic Materials - Texas A&M University - TAMU - Dr. Amir Saeidi | Latest Version | 2024/2205 | Rated A+ What is the primary purpose of annealing metallic materials? Annealing is used to relieve internal stresses, improve ductility, and refine the grain structure of metals. What is the significance of the yield strength in metallic materials? Yield strength indicates the maximum stress a material can withstand without permanent deformation, crucial for...
