For 10 points, name this measure of the intensity of forces acting on a deformable, solid body.
In cardiology, the value of this parameter increases with radius and decreases with wall thickness according to Laplace's Law. Knowing three vectors for this quantity in mutually perpendicular planes at a point allows for it to be calculated for any plane through that point according to Cauchy's theorem. Cauchy also lends his name to the second-order tensor used to represent this quantity, which has the normal ones on the diagonal and the shear ones off the diagonal. This value can be represented by Lame's ellipsoid but more commonly the normal and shear components are plotted against each other to find Mohr's circles. When this value passes the yield point, deformation occurs, and the ratio of it to strain is given by Young's modulus. Like pressure, it is represented as force per unit area.
