IMPLEMENTATION OF STRENGTH CALCULATION SOFTWARE BASED ON THE SEMI-ANALYTICAL METHOD OF FINITE ELEMENTS

One of the main and responsible stages creating an apparatus for numerical analysis structures using finite element method is its implementation in form a set programs. The principles complex construction should take into account modern requirements strength calculation software complexes. Among them, first all, automation computing process, rational use resources operating external memory storage devices, non-closedness relation to classes problems be solved, algorithms task input data, discretization solution systems equations etc. In addition, structure programs specifics semi-analytical elements, which such large experience developed mathematical support search spatial has not yet been accumulated, as when traditional version FEM. Considerable solving mechanics problems, accumulated over past decades, reflected number industrial commercial complexes domestic (LIRA, SCAD) foreign (ANSYS, Nastran, ABAQUS) production. base these allows you obtain solutions wide range deformable rigid body objects different dimensions, including massive bodies, convenient means input-output information processing obtained results make them very accessible circles users allow display with maximum degree visibility. There are also object-oriented created at manufacturing enterprises research institutes, example Institute Strength Problems National Academy Sciences Ukraine, Dnipropetrovsk University.
 conducted will determine most optimal ways listed from point view costs complexity implementation, well outline circle unsolved issues.
