A reusable frangible joint includes a first part having a hemispherical convex surface, and a second part defined by a reversely identical mating hemispherical concave surface. The convex and concave surfaces of the joint are secured and held together in compression until a predetermined applied load causes the joint to fail. The joint includes at least one replaceable fastener that rigidly secures and holds the respective concave and convex surfaces together. The fastener, designed to be the only part of the joint configured to fail, is sheared apart under the predetermined load, which results in separation of the concave and convex parts from one another irrespective of from which direction or to which part the impact load is applied. The failed fastener can then be replaced, wherein the frangible joint becomes immediately reusable, as having incurred no other damage by the impact load.
