Reference Entry
A definition of the term "Barba's law" is presented. It refers a law in physics, which was named after its discoverer. The law states that in a tensile test in which samples are tested to fracture, geometrically similar test pieces of a given material deform in a similar manner. If the test pieces are right circular cylinders, the same value for the elongation at fracture is obtained for samples of a given material provided that the ratio of the length to the diameter has the same value.

    A four-parameter family of self-similar solutions is obtained to the mean curvature flow equation for a surface. This family is shown to be stable with respect to a small deformation of a hyperbolic surface. At time instant t*, a singular point is formed within a finite time interval, that is...
