本文將離散元法用於計算和模擬各向異性材料在沖擊載荷下動態損傷和破壞過程。 -
The following results are achieved : ( 1 ) in accordance with the empirical electron theory of solids and molecules, considering the number of covalent bond pairs on the strongest bond in a segregation structure na, the elements for matrix - strengthening can be chosen. ( 2 ) on the basis of the available phase - equilibrium thermodynamics calculation of alloy system and phase diagrams, which have been worked out, the contents of alloy elements can be identified with reference to the types, quantity and phase - transformation of carbides. ( 3 ) both the values relating to toughness ( including bending strength, yield strength, impact value of unnotched samples ) and hardness of new dm9 die steel are higher than those of crl2mov die steel
結果得出： （ 1 ）根據固體與分子經驗電子理論，利用偏聚結構單元的最強共價鍵上的共用電子對數n _ a ，可以選擇工模具鋼基體相的強化元素； （ 2 ）根據合金系相平衡熱力學計算及已有的相圖，可以碳化物類型、數量及其相變確定合金元素含量； （ 3 ）新型dm9鋼在強韌性（抗彎強度、屈服強度、無缺口沖擊值）和硬度方面均高於cr12mov鋼； （ 4 ）以dm9鋼與6crw2si 、 7cr2wmovsi （ dm7 ） 、 h13和cr12mov四種模具鋼的實驗比較，進一步驗證了上述冷作模具鋼合金設計方案是合適的。
