“…According to certain specifications, we have opted for a Constant Tension Shear initially developed by Richard (Richard, 1981;Richard and Benitz, 1983) in order to obtain mixedmode configurations in isotropic and ductile materials Ma et al, 2006). In order to take into account orthotropic assumptions, Valentin and Caumes (1989) have adapted the geometry to orthotropic materials such as wood.…”

“…The FPZ could has various size and shape for different stress field in front of the crack that could influence determination of values of the fracture properties. Determination of the fracture properties of concrete is usually performed on common test configurations such as three-point bending or four point bending test with notch, see [17] [18][5] [19], the another configuration is wedge splitting test (WST [27][21] [15]), or wedge-splitting/bending test of notched specimens [29], CTS (compact tension shear) [9] [14] [16], composite compact tension specimen [24] etc. [25].…”

The objective of this study is to investigate the use of compact tension specimen calibration curves for evaluation data of fracture properties measurement performed on modified compact tension specimen made from cement based composites. From literature, the well-known calibration curve for compact tension specimen is compared with calibration curves for Modified compact tension specimen that are obtained from numerical calculation. The obtained results are quantified and accuracy of solution is discussed. The suggested curves could be preferably used for determining of the fracture parameters.

“…additional static loading, stress concentrators, crack propagation) seem to be advisable. 2,5,6,[10][11][12][13] Studies on behaviour of the material subjected to such loading should be helpful in prediction of element life and determination of optimum work conditions. 3,6,7 The mixed loading modes, being combinations of modes I and III, are often met in real machine structures, for example in various drive shafts.…”

A B S T R A C TThe authors analysed influence of a component of the torsional moment M as under the complex loading state, that is under bending with torsion, on fatigue life during initiation and propagation of fatigue cracks. Simulation of specimen life was performed according to the relationships describing the crack propagation rate and including the equivalent stress intensity factor range K eq . Under complex loading, increase of amplitude of the torsional moment M as for a given initial value of the resultant moment M aw0 caused a higher fatigue life of specimens made of 10HNAP and 18G2A steels. This fatigue life increase was described by a nonlinear equation, the parameters of which had been determined from the experimental results. The fatigue lives estimated according to the assumed models were compared with those obtained from tests.Keywords bending with torsion; equivalent stress intensity factor range; fatigue life; mixed mode loading.
