Perfect pre - processing and post - processing function is one of the main factors to evaluate the vitality and market value of the finite element analysis system surveying today development of finite element analysis technology, most of which concentrate on establishing fine user interface, also has some limitation on application, and especially, the research on the visualization of arbitrary cut - plane is always in ascendants to realize the visual processing on cut - plane needs reprocessing the results of finite element analysis which have get, so the algorithm is two parts : seeking the physical value of cut - plane and drawing 2d contours, the former, based on the theory of stress on " arbitrary inclined plane " in physical mechanics, use the method of linear interpolation method to get the coordination and physical value of intersection between cut - plane and element arris ; the latter, based on the tables on elements, nodes, stress and strain, summarize a rapid algorithm of generating 2d contours based on the grid. this thesis synthesizes there two parts and get a visual processing program under fortran
縱觀有限元分析技術的發展，目前大多集中在建立良好的用戶界面上的研究仍存在許多應用上的局限性，其中對任意剖面上可視化的研究仍處于方興未艾的階段。要實現任意剖面上可視化處理，必須先將得到的有限元計算結果進行再處理，因此在演算法上分為兩部分：求任意剖面上物理量值的演算法及二維等值線演算法。前一部分以彈性力學中「任意斜截面的應力」為理論基礎，利用線性插值方法得到截面與單元棱邊的交點坐標及交點物理量值；在此基礎上；根據已得到的單元及節點序號表、應力應變物理量表，總結出一種基於有限元剖分網格的快速生成二維等值線的演算法。 -
Based on the fem program on fracture of plane structure developed by professor fu xiaoling of ho hai university, a two demension damage and fracture finite program package which is programed in fortran 90 language is developed. the paper adopts the plane - eight - nodes isoparameters element and compute the developing law of the damage and macro - damage of plane structure under load. considering the original damage and tension and compression damage at the same time, the paper adopts the more reasonable concrete constitute relation of two demension and exponent function model
在河海大學符曉陵副教授所編制的平面結構斷裂有限元程序（ dl08p4 ）基礎之上，本文用fortran90語言編制的二維損傷-斷裂有限元程序包，程序採用平面八結點等參數單元分析計算平面結構在外荷載作用下損傷及宏觀裂縫的發展規律，考慮了混凝土結構體內存在著初始損傷和同時存在的拉、壓損傷，並且採用更為合理的具有損傷含義的混凝土二維本構關系（即正交異性損傷模型中的本構方程）和指數函數模型建立的並可進行拉、壓損傷可比性換算的損傷演變方程，較為真實地反映了實際情況。 -
