【正文】 rain in the model occurs near the point L of the path KL as in fig. 4 (on the right). A change of the maximum equivalent plastic strain near the point L within the first 100 cycles is depicted in fig. 5 for both material models used. A detailed investigation shows an almost linear increase of the equivalent plastic strain in the case of the ABAQUSown material model. However, the increase lies between and for the first 300 cycle. The application of the UMAT leads evidently to considerably higher plastic strains due to the creep and damage of the material. Note that the values of the variable PEMAG (the magnitude of the plastic strain) after the It heating are quite similar for both models, see fig. 5. The behavior of the maximum von Mises stress along the path KL for the first 10 cycles is illustrated in fig. 6 for both material models. For the same reason, the von Mises stress obtained using the UMAT is considerably less than in the case if the ABAQUSown model is applied. Note that the values of the von Mises stress are quite identical for both models after the Ist heating, see also fig. 6. The ABAQUSown model also leads to a material softening, which is however not as distinctive ( MPa/300 cycles) as in the case of the UtM4AT. Only more conservative results obtained under an application of the UM\AT are used below for the verification of some design rules. As follows from the curve depicted in fig 5, the magnitude of the plastic strain seems to reach a saturated value. However, to get a definite answer, more cycles (say 300) should be simulated. 隧道掘進(jìn)機(jī)的循環(huán)行為模式進(jìn)行了研究同時(shí)使用 Abaqus中,自己的材料模型上面所述的粘塑性材料模型考慮損害 [1]實(shí)施最近由 J.
