SummaryNishihara’s combined bending and torsion out-of-phase fatigue limit data are analysed. The Tresca shear stress failure criterion predicts strengths up to 30 per cent higher than observed. It thus appears that renewed attention should be given to the basic problem of developing reliable combined stress failure criteria. It is suggested that new test methods will be required for this purpose.

Material Information

Three-dimensional fatigue failure criteria for unidirectional fiber composites under states of cyclic stress are established in terms of quadratic stress polynomials which are expressed in terms of the transversely isotropic invariants of the cyclic stress. Two distinct fatigue failure modes, fiber mode, and matrix mode, are modeled separately. Material information needed for the failure criteria are the S-N curves for single stress components. A preliminary approach to incorporate scatter into the failure criteria is presented.

So as to design the pavement planer, it is necessary to study the milling performance of asphalt concrete. In this work, a coupled thermo-mechanical plane-strain large deformation orthogonal cutting finite element model is presented to simulate the asphalt concrete milling process and predict the stress and temperature field on the cutter. Chip separation is considered by applying shear fracture failure criteria and element deletion and adaptive mesh technique. Two contact pairs are defined. Contact pair 1 defines the milling path, and contact pair 2 defines to prevent the formed chip enter into the workpiece. The Johnson-Cook’s constitutive relation is adopted for the asphalt material. The cutter surface friction and heat conduction are considered. The computation indicates that the maximal cutting force will change from 3.967KN to 10.494KN if the cutting speed is between 1000mm/s and 2000mm/s for the pavement planer of BG2000.
