Strength of Materials
Terms important to testing the strength of materials
Terms in this set (17)
-the ability of a material to undergo large plastic deformation after yielding.
- the maximum force a member can carry before it fails.
- a common material used in structures (99% iron, 1% carbon)
- the increase in the length of a bar (strain) as it stretches.
-if the load is removed the material's deformation will return to zero.
-the maximum load a material can withstand.
-when a material does not undergo plastic deformation (ruptures without warning).
-the maximum compressive force a member can carry before it buckles.
-a failure that occurs when compression causes a member to bend sideways.
-failure that occurs when tension causes a member to tear into two pieces.
-when material undergoes large deformation with little change in load.
-if the load is removed the deformation is permanent.
-the force (stress) put on a member to test its strength.
-shows how a member deforms and fails as the load is increased.
-the surface area of the material exposed in a cross-section.
Modulus of Elasticity
The slope of the line in the linear elastic region created by the stress on the object divided by the strain.
-the point on the load-deformation curve where yielding begins.
