每週 (20241110) CAE分析練習 (Simufact.Forming)：鈑金成形極限CAE分析

使用Simufact.Forming進行鈑金成形極限CAE分析。

測試模型包括Nakajima (半圓沖頭)與Marciniak模型 (圓柱沖頭)，

試片形狀包括圓盤形與圓弧缺口形狀之試片。

從分析結果可以看到不同試片形狀具有不同的應變路徑，

圓盤形試片以雙軸應變爲主，而圓弧缺口形狀試片則以平面應變爲主。

Weekly (20241110) CAE simulation practice (Simufact.Forming): Simulation of Forming Limit Testing for Sheet Metal.

Use Simufact Forming to simulate the forming limit testing for sheet metal.

The testing models include the Nakajima model (hemisphere punch) and the Marciniak model (cylindrical punch)

The specimens include a circular disk and an arc-notched plate.

According to the simulation results:

The specimens include a circular disk and an arc-notched plate.

The circular, disk-shaped specimen primarily exhibits biaxial strain, while the specimen with an arc-shaped notch predominantly exhibits plane strain.
