Stress-Strain Curves Flashcards

Front

Strength

Back

the ability of a material to withstand force without breaking or bending

Front

Stiffness is when a material can...

Back

Hold its shape without bending

Front

This test applies pulling force to a material and measures the specimen's response to the stress.

Back

Tensile test

Front

The temporary change in length, volume, or shape produced when a force is placed on an object, after which the object retains its original shape.

Back

Elastic deformation

Front

The stress beyond which a material becomes plastic.

Back

Yield point

Front

What is the permanent distortion that occurs when a material is subjected to force beyond the yield point?

Back

Plastic deformation

Front

When a material is having hardness and rigidity but little tensile strength thus breaking readily with a comparatively smooth fracture.
