| Abstract: | By comparison with elasto-plastic materials, some problems in the programming for strain-softening analysis of quasi-brittle materials are studied. They include the principles and methods, loading step, iteration proceeds, the measures of reducing computation errors and etc. The functional and flow chart of the program using boundary element method is presented. Finally some fit examples are given. |
