Although numerical methods have frequently been used in the study of frc , theoretical analyses of such test methods as pull out tests and single fiber fragmentation tests , seemingly simple , remain to be challenging problems . problems arise when other factors are considered in connection with the various numerical models . these factors include nonlinearities in the properties and / or geometries of the materials , influences of such environmental conditions as temperature ( which is also to be studied in the present work ) 本论文正是针对以往研究中的不足,在对纤维增强复合材料破坏问题进行数值模拟的研究中,综合考虑了纤维和基体材料的非线性效应、纤维和基体材料受外载发生大变形时的几何非线性,以及纤维基体之间界面脱粘时接触单元的非线性效应。
