Abstract

A device for dissipating energy consists of tubes or rods laid alternately in different directions, joined at points where the tubes or rods are in contact and placed between two plates. If the distance between two tubes or rods of one row is f, the sepn. between those of two neighbouring parallel rows is f/2. The nagle between the directions of the alternate rows is 45-135 degrees. The device allows mechanical shocks to be absorbed. The shocks can result from a falling piece accidentally striking a fixed unit e.g. the reinforced concrete wall of an enclosure protecting a nuclear reactor, or pipe system. The appts. is efficient while being simple and incurring relatively low costs. IT ensures great stability, and is capable of giving a correct deformation curve responding to the partic. application.
