Paper abstract bibtex

The objective of this work is to predict the crack opening and closure behavior induced by plasticity. Numerical procedure (by means of finite element method) is conducted using ANSYS with APDL as added code that regulate crack propagation process automatically. The main work comprises of the following items. Elastic-plastic specimens are modeled by 2D middle-crack tension M(T) and compact tension C(T). Element mesh mapping is controlled by modified-LESIZE option. Cyclic plasticity is stored in fix number elements. Crack opening and closure are simulated by using node fixity. The preliminary results are compared with previous numerical and experimental result to verify the procedure. By using bilinier-kinematic-hardening material constitutive that represents aluminum high strength alloy, the effect of cyclic load ratio R, and plastic modulus H (strain hardening material) are analyzed concerning to crack opening pattern and crack closure. The crack opening pattern on minimum loading is increased 0.0015mm for M(T) and 0.001mm for C(T), on average, by increasing cyclic load ratio R from 0.5 to 0.8. In contrary, the crack closure is reduced by increasing cyclic load ratio R‥ Also, the crack closure is reduced 0.1 by increasing plastic modulus H from 0.3E to 0.5E. iv
