Good Stuff Happens in 1:1 Meetings: Why you need them and how to do them well
Mechanical behavior material science and engineering

3. Pure shear : when a material elongates or stretches in one direction then shorten in the perpendicular direction.
there is a rotation happening
Simple shear : when one layer of a material slides over another layer while bottom layer remain fixed.
there is no rotation happening
4. The yield point is the stress at
which a material begins to
deform plastically.
Below this point, the
material will deform
elastically,
However, some materials, such as copper and certain aluminum alloys, do not
have a well-defined yield point. Their stress-strain curve transitions gradually from
elastic to plastic deformation
In such cases, an offset
yield point (or proof
stress) is defined as the
stress at which a certain
amount of plastic
deformation occurs.
