Deformation (Dynamics)¶
In physics and continuum mechanics, deformation is the change in the shape or size of an object.
Contents:
- Bulk modulus via Young modulus and Poisson ratio
- Elastic energy density of bulk compression via pressure
- Elastic energy density of compression via strain
- Engineering normal strain is total deformation over initial dimension
- Poisson ratio is transverse to axial strain ratio
- Pressure is Maclaurin series of strain
- Rotational stiffness is torque applied over angle
- Superposition of small deformations
- Tensile stress is Young’s modulus times strain
