ABSTRACTThe triaxial stress field has been measured along the centre line of a compact tension specimen in the direction of cracking. The specimen had been subjected to ∼60,000 cycles at δK=31 and Kmax = 34 MPa mm½ and was bolted open at maximum stress. The field was remeasured after the stress had been fully relaxed. The results are discussed in terms of expectations from fracture mechanics calculations.

Simulation Results

This article studies the fracture behavior of compact tension specimens under tensile loading. The test - numerical hybrid method is used to explore the effect of the location of the loading hole. And the size effect is also considered to analysis the reason of fracture behavior .The initial load for numerical simulation is based on the experimental data. In that case, the numerical simulation results can be used to study the effect of the location of the loading hole and also the size effect to the specimens.

Linear Fracture

The paper deals with the accordance's comparison of resources and results of several commercial and solid mechanics numerical modelling software. One of the most common fracture mechanics example is Compact Tension Specimen (CTS) which is used in this paper for testing and comparing the results of commercial solid mechanics numerical modelling software (for instance SolidWorks module CosmosWorks, Unigraphics NX technical analysis module, etc.) using nontrivial examinations to their possibility margins. Standard Griffith (A.A.Griffith) model of energy balance is used in linear models which explores the mesh size influence to the precision of results. Achieved results have been compared mutually and with the examples found in the literature.
