5.1.2.1 Applications
1. Design of structures and manufactured products to reduce weight
while maintaining required structural, functional, and manufactur-
ing characteristics.
2. Optimization of component thickness and shape based on user-
defined objective and constraints.
3. Structural and product design constrained by size, weight, fre-
quency, and so on.
4. Feasible structural and product designs subject to size and shape
constraints.
5. Design of structures and manufactured products for minimum cost,
weight, or size.
5.1.2.2 examples
A few examples of optimization are listed as follows:
1. Optimization of structural crashworthiness behavior, for example,
automotive industry, aviation and aeronautical industry, transporta-
tion safety, and so on.
2. Optimization of sheet metal forming processes, for example, opti-
mization of tool geometry with respect to springback compensation.
3. Identification and optimization of material parameters in nonlinear
material models.
5.2 design oPtimization using ansys
The optimization module is an integral part of the ANSYS program that
can be employed to determine the optimum design. The ANSYS program
can determine an optimum design, a design that meets all specified require-
ments yet demands a minimum in terms of expenses such as weight, surface
area, volume, stress, cost, and other factors. An optimum design is one that
is as effective as possible. Virtually any aspect of design can be optimized:
