DSI Celebrates 50 Years

dynamic system inc. Dynamic Systems Inc. is dedicated to advancing the state-of-the-art in dynamic thermal-mechanical testing of materials and simulation of processes. Founded in 1957 to develop and manufacture a system for thermal metallurgical studies, DSI has a long history of pioneering the physical simulation of dynamic thermal and mechanical processes.

DSI’s first system, christened the "Gleeble" by one of its creators, was originally developed to simulate the heat-affected zone of arc welding. A pneumatic system was soon added to the Gleeble, giving it limited mechanical capabilities. In 1979, the Gleeble became the first machine ever to combine full resistance heating thermal capabilities and hydraulic servo-mechanical testing performance in a single system. In the early 1980s, the machine was re-engineered to incorporate computers for controlling tests and collecting data. Since then, an advanced series of systems, which combine dynamic thermal and mechanical testing under sophisticated computers for control and data acquisition, has been introduced by DSI.

As a result of this innovative technology, it is now possible for materials to be tested in the same dynamic way that they are fabricated and used. This capability is producing new insights into materials science and new breakthroughs in productivity.
