The Technogrid is a strain energy absorption device which absorbs the kinetic or potential energy of a moving object by deforming a metal grid of known design and characteristics through a stroke deformation of predicted value.  Typical Force Energy curves are shown below.

TheTechnogrid is a series of multi bar units that are connected in a staggered grid shape. On impact, the grid bars will yield and deform under double curvature bending.  The yielding of the bars is what allows the units to "open up" or stroke.

Technogrid can be calculated and designed to suit the application.  Safe deceleration and high end forces can be controlled for a wide range of energies.  The optimum configuration of the units can be achieved by combining the grids in series or parallel to suit the application.
