Separation at the interface of a circular inclusion embedded in a matrix of lower characteristics impedance and subjected to incident compressive waves is investigated, both experimentally and analytically. In the experiment, the compressive waves were generated by small explosive charges. The qualitative analytical treatment is based on the methods of propagating stress discontinuities. It is shown that a compressive stress wave is converteed into a tensile wave after a refraction and a reflection inside the inclusion. The results of this paper apply to the behavior of fiber-reinforced composites under dynamic loading conditions. (Author, modified-PL).

Abstract: "During the assembly of a product, it is vital that the partially completed assembly be stable. If the assembly is unstable, then it must be fixtured to stabilize it before retrieving the next part and inserting it. This paper presents a stability test and a new approach to automatically generating the positions of a small set of fixture elements (fixels) that will stabilize a frictionless assembly with respect to a given externally applied force and moment (e.g., gravity and part insertion forces). The stability test and the fixel positioning approach consider both the translational and rotational degrees of freedom of each part. Since all the relevant mechanical constraints are linear functions of the contact force magnitudes and the components of the velocities of the parts, linear programming techniques can be used with great efficiency."
