... The final designs are better because they are based in quantitative physical science. The vision is a physical-science-based, mathematically expressed design methodology that can be used by manufacturing engineers to create designs of manufacturing processes with the same confidence that structural engineers now use elasticity-based methods to create designs of bridges and buildings.

... These complex and physically detailed constitutive relations provide a rich basis for concurrent design of materials and their processes, but such detail is usually unnecessary for good design of a process for a particular material. In fact, it is often desirable, because of the computational simplification that can be achieved, to perform preliminary design with the simplest possible constitutive models such as Newtonian fluids, linear hypoelastic solids, and rigid/perfectly plastic solids.

... The material aspects of the computer simulations are contained in constitutive equations that describe the evolution of the material as well as its current response. Development of the constitutive equations as well as the full process simulation involves computational mechanics.
