Strain and Various forces
, • Strain: It is defined as a non-dimensional
deformation which measure the change of
relative positions of the parts of a body under
any cause.
– Normal Strain: The ratio of the change in length to
the original length of a linear element is known as
the normal strain
– Shear Strain: It is measures in terms of change in
angle between two linear elements from
undeformed state to deformed state.
