On ther other hand, the Charpy impact energy obtained directly from experiment and that from the simulation are compared in Table 8. But the magnitude of the notch radius has the same influence on the stress triaxiality. The height of pendulum after impact is recorded, and the energy difference before and after the impact can thus be calculated. Received May 7; Accepted Jul Aluminum alloys, with low density, high strength to weight ratio, good ductility and excellent corrosion resistance, are widely used in aviation, aerospace, automotive, machinery manufacturing etc. Validation of the J-C fracture model In this paper, a calibration methodology is proposed to obtain a simplified J-C fracture model to describe the ductile fracture more accurately. During the impact, part of the mechanical energy is dissipated by specimen deformation and fracture. Fig 3 c shows a specimen sandwiched between the incident bar and transmission bar. J-C fracture model parameters for the common method and calibration are listed in Table 7. The values for each B and n can be directly obtained as parameters a and b respectively.

    However, those few published studies of the fracture criterion coupled with dynamic constitutive mechanical behavior cannot match the increasingly engineering application of AAT6.

    The central zone of the fracture surface shows ductile fracture full of bumps and hollows while the residuary area represents shear fracture with the surface along the maximum shear stress plane, at an angle of 45 degree to the tensile axis.

    The Johnson-Cook failure criterion [ 17 ] has been widely used to study the dependence of fracture strain on the strain rate, stress triaxiality, and temperature through both experiments and numerical simulations. Ludwik P, Scheu R. But the magnitude of the notch radius has the same influence on the stress triaxiality.

    According to the principles of one-dimensional elastic-wave propagation in slender bars, the engineering stress, the engineering strain and the strain rate can be calculated from the reflected and transmitted wave amplitude via the following equations [ 10 ].

    The limit stresses are presented in Table 2. The quasi-static tensile test data of smooth and notched specimens is used to fit the first three constants, D 1D 2 and D 3. Compared with others AA6xxx aluminum alloys exhibit a rather low rate sensitivity, while AA7xxx alloys show moderate rate sensitivity.

    In this work, a method combining experimental data and numerical simulations was applied to obtain the stress triaxiality history along the entire experiment.

    It is common view that the dimple fracture experiencing the process of nucleation, growth, and coalescence of voids and shear fracture developed from shear band localization are two primary fracture forms for ductile materials.

    On ther other hand, the Charpy impact energy obtained directly from experiment and that from the simulation are compared in Table 8.

    Thus, the constant in the temperature-dependent factor is neglected, then the formula, with four constants left to identify, is simplified as Eq 9. Fig 6. This Data is indicative only and as such is not to be relied upon in place of the full specification.

    Johnson-Cook fracture model constants identification The construction of the J-C fracture model implies that five constants must be identified see Eq The height of pendulum after impact is recorded, and the energy difference before and after the impact can thus be calculated.

    Notched specimen tensile tests Studies [ 14 — 20 ] have been performed in the past that proved fracture ductility depends markedly on the triaxiality of the stress state. A similar result is obtained, that is, little rate sensitivity is observed on the mechanical response of AA In this case the rate of temperature change is calculated through.
