Hooke's Law

When the applied force is proportional to the deflection, a material is said to obey Hooke's law. There is a linear relationship between the force and displacement and thus, linear elastic materials obey this law.


Hypothesis of the material continuity

is the case, when the material is uniformly distributed in a whole body volume


Hypothesis of the material homogeneity

is the case, when all points of the body have the same material properties


Hypothesis of the material isotropy

is the case, when the material properties are the same in each direction of a body
