ONE-DIMENSIONAL MATERIAL THEORY

We consider at first a uniaxial tensile or compression test. For such a test, one often uses samples with rotational symmetry, which are clamped at the (thicker) ends, and have a middle region that is long enough to apply the measuring device so that we can assume a uniaxial state of stress. A cylindrical form shall keep the inhomogeneities as low as possible so that we can assume a homogeneous state of stresses and strains.
