Ductile 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...

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...

GE 2000 Exam 2 MTU Questions and Answers brittle, ductile, and elastic strain - CORRECT ANSWER-faulting - broken block flow - stretched back elastic - reversible, not permeant effect on material elastic limit - max stress before permanent effect ductile - irreversible permanent change in shape or volume rupture/fracture - material breaks the factors that affect the strain a rock experiences - CORRECT ANSWER-rock composition confining stress (d...

Earth Science Lab Final (Answered) Complete Verified Solution Noncomformity 1) Younger sedimentary rocks on top of older metamorphic or intrusive igneous rocks 2) Imply period of uplift of deeply buried rocks Three types of uncomformities angular uncomformity, disconformity, and noncomformity Radiocarbon dating Using the carbon-14 isotope to date very recent events (Half-life of carbon-14 is only 5,730 years) (Only useful for dating events from historic past and very recent geolog...

MMET 207 Exam III Questions and Answers | Latest Update | 2024/2025 | Graded A+ What is one key characteristic that distinguishes ductile materials from brittle materials? Ductile materials can undergo significant plastic deformation before fracture, while brittle materials fracture with little to no deformation. What is a notable advantage of using aluminum in structural applications? Aluminum is lightweight yet strong, making it ideal for applications where reducing weight is cru...

MMET 401: Exam 1 Questions and Answers | Latest Version | 2024/2025 | Rated A+ How do mechanical properties influence the behavior of materials under stress? Mechanical properties, such as tensile strength and elasticity, determine how materials deform and fail under applied forces. What role does the stress-strain curve play in understanding material behavior? The stress-strain curve illustrates how a material responds to stress, providing insights into its elasticity, yield point...
