Brittle deformation - Study guides, Class notes & Summaries

Deformation CORRECT ANSWER Refers to all changes in the size, shape, or position of a rock body in response to stress. Confining pressure CORRECT ANSWER equal in all directions, associated with the weight of the overlaying rocks. Differential stress CORRECT ANSWER not equal in all directions, associated with tectonic activity. can any rock deform in a brittle or ductile manner? CORRECT ANSWER Any rock can deform in a brittle or ductile manner, depending on the conditions of the deformat...

What is the description of damage of a brittle fracture? correct answersSudden rapid fracture under stress (residual or applied) where material exhibits little or no evidence of ductility or plastic deformation What type of Steel are of primary concern with brittle fractures? correct answersCarbon and low alloy steels. 400 series SS are also susceptible What has a significant influence on toughness and resistance to brittle fractures? correct answersSteel cleanliness and grain size In m...

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 ...

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...

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...

MMET 207 Exam 1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ What is the primary purpose of metallography in material science? Metallography is used to analyze the microstructure of metals, which helps in understanding their properties and performance under various conditions. What effect does strain rate have on the ductility of metals? Increasing the strain rate generally decreases the ductility of metals, leading to more brittle behavior during deformation. I...
