摘要：

A method of simulating the age forming of initially flat panels is proposed. It conceptually divides the process into three phases (loading, aging, and unloading) and simulates each phase separately. Some sample simulations are presented for 7075 aluminum alloy based on a simplified version of the general procedure (linear-loading and unloading, nonlinear aging). The results of these simulations are used to illustrate several aspects of the predictions. An interesting finding is that the part shape and tool shape are geometrically similar in tow important special cases.
