    基于多尺度晶体塑性有限元的GCr15轴承钢拉-压不对称性研究 by 樊冬, 余丰, 李淑欣

    Published 2021-01-01
    “…In this paper,stress triaxiality is added to the classical crystal plasticity constitutive model to investigate the experimental phenomenon of tension-compression asymmetry for the GCr15 bearing steel.Firstly, the crystal plasticity constitutive model is extended by considering the effect of stress triaxiality on yield criterion and flow rule in each slip system.Secondly,representative volume element( RVE) was simulated to regenerate the quasi-static uniaxial tensile and compression engineering stress-strain curve of GCr15 bearing steel by using crystal plasticity finite element method.The results show that stress concentration occurs at the grain boundary due to the crystal orientation difference among polycrystalline grains,and under the influence of triaxial stress state,the RVE simulation results show that the stress concentration has a significant effect on tensioncompression asymmetry.Therefore,it is concluded that the effect of stress triaxiality on the texture of mesoscopic crystal is an important factor that causes the phenomenon of tension-compression asymmetry.…”

    Virtual network function deployment strategy based on improved genetic simulated annealing algorithm in MEC by Zhuo CHEN, Gang FENG, Yijing LIU, Yang ZHOU

    Published 2020-04-01
    “…In order to effectively improve the end-to-end service delay of the flow in multi-clusters coexisting mobile edge computing (MEC) network,a virtual network function deployment strategy based on improved genetic simulated annealing algorithm was proposed.The delay of mobile service flow was mathematically modeled through the open Jackson queuing network.After proving the NP attribute of this problem,a solution combining genetic algorithm and simulated annealing algorithm was proposed.In this strategy,the advance mapping mechanism avoids the possibility of network congestion,and the occurrence of local optima was avoided through using the methods of individual judgment and corrective genetic.Extensive simulation was set up to evaluate the effectiveness of the proposed strategy under different parameter settings,such as different volume of requests,different scale of service nodes,different number of MEC clusters,and logical link relationships between virtual network functions.Results show that this strategy can provide lower end-to-end services delay and better service experience for latency-sensitive mobile application.…”
