摘要
通过给出混凝土复合型裂纹的开裂判据,对裂纹在单元间的扩展作出假定。采用基于Fortran语言的扩展有限元程序对混凝土侵彻过程中的裂纹扩展进行数值模拟,并对结果进行工程分析,揭示了裂纹扩展规律,展示了扩展有限元法在裂纹扩展分析中的独特优势。
Concrete is a composite based on penetration of concrete has construction material used widely in always been a hot issue in academia. engineering. Crack growth Crack propagation problems has been studied in-depth based on the following methods and assumptions： the fracture criterion for mixed mode crack; the crack runs though the unit; the numerical simulation based on the Fortran and engineering analysis. The results reveal the expansion law, showing its unique advantages in the crack propagation analysis.
