| 1 | YIELD SURFACES AND PLASTIC FLOW OF 45 STEEL UNDER TENSION-TORSION LOADING PATHS显示文摘An experimental analysis on the subsequent yield-surfaces evolution using multiple specimens is presented for a 45 steel after a prescribed pre-strain loading in three different directions respectively, and the yielding is defined by a designated offsetting strain. The size of the subsequent yield surface is found smaller than the initial yield surface; the negative cross effects are observed in the normal loading direction, its shape is not a Mises circle but has a rather blunt nose in loading direction and flat in the opposite. These results strongly depend on the loading path and the prescribed offset plastic strain. The plastic flow direction to the subsequent yield surface is investigated, and it is found that the plastic flow direction deviates from the normal flow rule. The deviation differs from preloading case to preloading case. And the plastic flow direction would have a larger deviation from the normal of the yield surface, if the subsequent yield was defined by a smaller offset strain. Furthermore, the experiments are simulated using the Chaboche model, and the results show that it can rationally predict yield-surface only when yield is defined by a fairly large offset strain. | Guijuan Hu Keshi Zhang Shihong Huang Jiann-Wen Woody Ju | 2012 | Acta Mechanica Solida Sinica2012，25，4： | 5 |

| 4 | APPLICATION AND THEORETICAL ANALYSIS OF C/SiC COMPOSITES BASED ON CONTINUUM DAMAGE MECHANICS显示文摘Based on the thermodynamic theory,an orthotropic damage constitutive model was developed to describe the nonlinear mechanical behavior of C/SiC composites.The diferent nonlinear kinematic and isotropic hardening functions were adopted to describe accurately the damage evolution processes.The damage variables were defined with the damaged modulus and the initial undamaged modulus on energy equivalence principle.The initial orthotropy and damage coupling were presented in the damage yield function.Tensile and in-plane shear loading and unloading tests were performed,and a good agreement between the model and the experimental results was achieved. | Yanjun Chang Guiqiong Jiao Keshi Zhang Bo Wang Jiannwen Ju | 2013 | Acta Mechanica Solida Sinica2013，26，5： | 3 |
| 5 | On the tension necking of copper single crystal specimen under slip deformation mechanism显示文摘The tension necking of FCC copper single crystal specimen with a square cross section was analyzed under the slip deformation mechanism. The actual clamp manner of the specimen was modeled by setting correlative boundary condition,and the small angle deflection between tension loading axis and crystallography axis [100] was taken into account. The finite deformation numerical analysis of three-dimensional necking deformation for the specimen was performed by apply-ing crystal plasticity theory associated with a numerical algorithm suggested by the first author. According to the comparison with experimental observation,the fact was confirmed that the numerical results could describe the loading elongation curve of the copper single crystal specimen under large strain tension reasonably,and the method could be used to investigate the necking characteristic in neck shape and the effect due to the small angle deflection. Further,the investigation into the influence of specimen cross-section shape on necking was also performed;the results on mechanical response and neck profile evolution obtained through modeling of cylindrical specimen were compared with those obtained with square cross-section specimen. | ZHANG KeShi GENG XiaoLiang LI JinShan HU Rui | 2007 | Science China(Technological Sciences)2007，50，3： | 2 |

| 16 | Fracture Analysis of Cast Iron Materials with Cracks Based on Elastoplastic Extended Finite Element Method显示文摘Based on the ABAQUS platform for finite element analysis, the extended finite element method (XFEM) considering elastoplastic constitutive relationship is developed, by which the displacement discontinuity across the crack surface and the strong nonlinearity near the crack tip can be described more accurately. The strip specimens with unilateral cracks and central cracks under uniaxial tension are simulated using the XFEM and the FEM, respectively. The J-integral across the crack on each incremen t is calcula ted using the equivale nt domain integral met hod (EDIM), the interaction integral met hod and the FEM, respectively. The effec ts of mesh size and mesh shape near the crack tip, element type and different calculation methods on the accuracy of J-integral are analyzed. The simulation results show that the XFEM is more accurate than the FEM with the same element size and type. The fracture tests of cast iron specimens with unilateral cracks under uniaxial tension are performed, and the J-integral criterion is valid to predict the fracture initiation in numerical simulation. The critical value of J-integral is calculated using the EDIM of the XFEM. The comparisons demonstrate that the simulated elastoplastic load-displacement curves with the XFEM are in good agreement with the experimental results. | Yanjun Chang Qiao Song Zheng Kuang Keshi Zhang Zhanguang Zheng | 2019 | Acta Mechanica Solida Sinica2019，32，2： | 1 |
