Characteristics of Materials

Front

What is the definition of Strength in materials?

Back

The ability of a material to withstand an applied force without breaking or permanently deforming.

Front

What is the definition of Stiffness in materials?

Back

The resistance of a material to deformation under an applied force.

Front

Give examples of stiff materials.

Back

Glass, steel rods, carbon fiber.

Front

What is the definition of Elasticity in materials?

Back

The ability of a material to return to its original shape and size after the deforming force is removed.

Front

What is the Elastic Limit?

Back

The maximum force a material can withstand and still return to its original shape.

Front

What do elastic materials obey up to the elastic limit?

Back

Hooke's Law.

Front

Give examples of elastic materials.

Back

Rubber bands, springs, elastic cords.

Front

What occurs after the elastic limit is exceeded?

Back

Plastic deformation.

Front

What is the definition of Ductility in materials?

Back

The ability of a material to be drawn into a wire without breaking.

Front

What happens to ductile materials before breaking?

Back

They undergo significant plastic deformation.
