	Spring, 2007	Microstructure prediction has been a high priority development priority for years. An example of CA microstructure prediction is discussed.
	Winter, 2007	Die wear has been the subject of researchers for years. An excellent production application, courtesy of Formtech is summarized.
	Fall, 2006	DEFORM-2D Version 9.0 and DEFORM-3D Version 6.0 are summarized. An overview of press behavior (movement control) functionality is summarized. An excellent example of production cutting (machining) simulation is show.
	Spring, 2006	A very sophisticated DEFORM-HT simulation from the CASH Project in Germany is summarized.
	Winter, 2006	DEFORM is used in a wide range of aerospace applications. Boeing 777ER applications are highlighted after a world record flight.
	Fall, 2005	DEFORM-F2 is the 'next generation' replacement for DEFORM-PC after nearly eleven years in production. DEFORM-F3 provides an extremely easy-to-use three-dimensional simulation system for small to mid-sized companies moving into 3D simulation. A project summary of a task within the PRO-FAST Project is included. In this case, a thin walled pipe upsetting operation was optimized in the production of Mk 84 bomb cases.
	Summer, 2005	DEFORM-3D has been used to model the process of tube piercing. A specialized updating algorithm using lagrangian and ALE has been developed to reduce computation time without sacrificing accuracy in this complex process. Simulating this process was impractical in the past. Additionally, a summary of DEFORM-3D / DEFORM-F3 version 5.1 and DEFORM-2D / DEFORM-F2 is included.
	Spring, 2005	Heat transfer has been included in DEFORM, since its' inception in the late 1980's. Conduction, convection and radiation have a significant influence on material flow, microstructure, process times and product quality. In times of rapidly rising energy costs, heating times are being examined closely by leading companies. A review of heat transfer fundamentals and the influence of view factors is presented.
	Winter, 2005	DEFORM developments continue to be based on user requirements. DEFORM-HT can be used to model grain size in superalloys. Developing optimum grain size is critical to the mechanical properties. An example of a 3D machining simulation is included.
