Numerical analysis of interface crack problem in composite plates jointed with composite patch
Fatih Cetisli,Mete O. Kaman 국제구조공학회 2014 Steel and Composite Structures, An International J Vol.16 No.2
Stress intensity factors are numerically investigated for interfacial edge crack between two dissimilar composite plates jointed with single side composite patch. Variation of stress intensity factor under Mode I loading condition is examined for different material models and fiber orientation angles of composite plates and patch. ANSYS 12.1 finite element analysis software is used to obtain displacements of crack surfaces in the numerical solution and repaired plates are modeled in three dimensions. Obtained results are presented in the form of graphs. It is found that fiber orientation angle of composites is an effective parameter on interfacial stress intensity factor.
Numerical analysis of center cracked orthotropic fgm plate: Crack and material axes differ by θo
Mete Onur Kaman,Fatih Cetisli 국제구조공학회 2012 Steel and Composite Structures, An International J Vol.13 No.2
In this study, fracture analysis of orthotropic FGM (Functionally Graded Material) plate having center crack is performed, numerically. Material axis arbitrarily oriented and there is an angle θo between material and crack axes. Stress intensity factors at the crack tips for Mode I are calculated using Displacement Correlation Method (DCM). In numerical analysis, effects of material properties and variation of angle θo between material and crack axes on the fracture behavior are investigated for four different boundary conditions. Consequently, it is found that the effect of θo on stress intensity factor depends on variation of material properties.
