Beam Contact Model

P-Beam

A pebbled beam (P-beam) is defined as a string of spherical balls for which the beam contact model exists at all ball-ball contacts. A P-beam provides the structural behavior of a prismatic and bisymmetrical beam composed of isotropic, linear elastic material. A P-beam is defined by the string of balls, and the ball densities (used along with ball radii to obtain ball mass). The structural properties of a P-beam are defined by the properties of each beam contact model in the string.
