  1. This thesis briefly analyzes some yield criteria and instability criteria to the sheet metal forming first. then according to the transformation rule from ultimate strain to ultimate stress, it establishes the mathematical calculation models of the forming limit stress diagram for the software development according to hill48 、 hill79 and hosford yield criterion irrespectively

    本文首先分析了板料成形的屈服準則和失穩準則，然後根據極限應變到極限應力的轉換關系，分別採用hill48屈服準則、 hill79屈服準則和hosford屈服準則，建立了用於軟體開發的成形極限應力圖的數學計算模型。
  2. First read in the calculation result file i. e. d3plot, then input the correlative material parameters and ultimate strain from experiments, and the developed software will produce the forming limit stress diagram used as sheet metal instability criterion and the stress contour of the part

    所開發的應用軟體，首先讀取dynaform的計算結果文件d3plot ，輸入材料的相關參數和試驗所得到的板料的極限應變，軟體即可生成用作板料失穩判據分析用的成形極限應力圖和零件的應力雲圖。
  3. In view of the above reason, this thesis adopts the forming limit stress diagram as the instability criterion due to its independence of strain paths, which is acknowledged at home and abroad in the field of sheet metal forming, and develops the applied software for the special purpose finite element analysis code dynaform in order to provide it with a new instability criterion

    本文基於板成形專用有限元分析軟體dynaform ，以國內外板料成形領域認同的具有應變路徑獨立性優點的成形極限應力圖為判據進行了應用軟體的二次開發，以期為板成形有限元分析軟體提供一個新的失穩判據。
  4. Stress strain diagram
