Engineering Material Properties
By Kyle Smith
Slide 1 - Slide
Recall three key points from the previous lesson.
Slide 2 - Mind map
Material Properties
and their definitions.....
Slide 3 - Slide
What Do you know about a materials 'strength'?
Slide 4 - Mind map
STRENGTH
The ability of a material to resist external forces. It is called
tensile, compressive, or shear strength depending on the load.
Slide 5 - Slide
What do you know about 'material toughness'?
Slide 6 - Mind map
TOUGHNESS
Ability of a metal to absorb energy and deform plastically
before fracturing.
Work per unit volume required to fracture a metal
and is equal to the area under the stress strain curve.
Slide 7 - Slide
What does 'elasticity' mean in terms of a material?
Slide 8 - Mind map
Elasticity
The ability of a material to return to its original form after
the load has been removed.
Slide 9 - Slide
Describe the terms -Hardness and Brittleness in your own words.
Slide 10 - Mind map
Hardness
The property of metal to resist being permanently deformed.
This is divided into three categories, resistance to penetration, resistance
to abrasion and elastic hardness.
Slide 11 - Slide
Brittleness
The property of materials to not deform under load, but
to break suddenly, for example, cast iron and glass are brittle. Brittleness
is opposite to plasticity.
Slide 12 - Slide
Plasticity
The quality of material such that it can be deformed without
breaking. Clay is completely a plastic material. Metals exhibit plasticity
in varying amounts.
Slide 13 - Slide
Based on todays class, state two new things you have learned and why.
Slide 14 - Open question
