... to a higher value in different test cases until the material failed. The alternating stress data shown in Table 3 are obtained from relevant literature [ 23 , 24 ] and are utilized for the fatigue simulation. Table 3 Alternating stress data for the unnotched Onyx and ABS specimen [ 37...

... Orientation Distribution Function (ODFs) and the same were simulated using different Taylor type deformation texture models. A strong difference in bulk texture developments was observed at respective strain paths. The textural differences largely explain the changes observed in normal anisotropy values...

.... The sliding direction after impact is calculated. A simulation of the impact of beam with a surface is developed and the velocity of separation, force of impact and kinetic energy of the beam after impact are studied for different incident angles of the beam. The incident angle is varied from 0 deg to 57 deg...

... are correlated and compared with the findings of the FEM simulations. All numerical, analytical, and experimental results illustrate that the fracture behavior of the laminate cantilever beam is dominated by mode II, mainly due to the effect of a large contact zone. The latter is determined by geometric...

...K. M. Liew, Fellow ASME; H. Tan; M. J. Tan In this paper, a constitutive equation for superplasticity, which is based on the microstructural mechanism of superplastic deformation taking into account the effects of deformation damage, is incorporated into the finite element method to simulate...

...L. Bruno; F. M. Furgiuele; G. Sciume´ A FEM analysis was carried out to study the mechanical behavior of a hard coating subjected to a nanoindentation test performed with a Berkovich indenter. The nanoindentation test was simulated by FEM code MSC Marc. The case study is a coating of CVD (Chemical...

... with and without preheating. Residual stresses were computed by numerical simulation and measured using the crack compliance method. For non-preheated specimens simulation and experiment agreed well and showed that extremely high residual tensile stresses were present in the laser melted material. By contrast, pre...

...David H. Lassila; Mary M. LeBlanc; Gregory J. Kay An apparatus has been developed for performing compression deformation experiments on oriented metallic single crystals to provide data for validation of 3-D dislocation dynamics simulations. The experiment is performed under conditions that allow...

... undeformed areas. Comparisons are drawn with results of 3D crystal plasticity calculations performed on digitized grain structures that conform to representative microstructures in terms of initial grain size and shape distributions. The crystal plasticity simulations predict regions of relatively large...

...H.-M. Huang; S.-D. Liu; S. Jiang A drawbead model with sheet metal passing through multiple bending-unbending processes was employed in this study to understand the springback phenomenon and to develop a numerical simulation technique for more accurate prediction of the springback process...
