Study Notes
Material Behavior Tests
- The three-point bending test measures the behavior of materials subjected to simple beam loading.
- The elastic behavior of materials often shows a linear relation between stress and strain.
Engineering Strain
- The definition of engineering strain (ϵ) is the ratio of change in length to the original length of the material.
Strain Ratios
- The ratio of the lateral and axial strains is called Poisson's ratio.
Material Deformation
- Plastic behavior occurs when the material undergoes permanent deformation without breaking.
- Elastic deformation is nonpermanent and the piece returns to its original shape when the applied load is released.
Pure Shear Tests
- The torsion test measures the behavior of materials subjected to pure shear force.
- The variation of pure shear in which a structural member is twisted is called torsion.
Stress and Strain
- The degree to which a structure deforms or strains depends on the magnitude of an imposed stress, which is known as stress-strain behavior.
