STUDY ON THE LOW-VELOCITY IMPACT AND RESIDUAL COMPRESSIVE STRENGTH OF HYBRID COMPOSITE SANDWICH STRUCTURES (MT)

Autor: ZHANG ChaoFeng, HAN ChaoChao, ZHU JiaJia, DU WeiZhong

Publikováno v: Jixie qiangdu, Pp 646-652 (2023)

The impact characteristics and residual compressive strength of the honeycomb sandwich structure under different impact energies and different boundary conditions were studied by testing and finite element analysis. The Vumat subroutine was used to e

Resource allocation based on sleep strategy in heterogeneous networks

Autor: Zhu Jiajia, Wu Runze, Tang Liangrui

Publikováno v: Dianzi Jishu Yingyong, Vol 44, Iss 10, Pp 127-130 (2018)

This paper focuses on a multi-objective optimization approach for resource allocation based on sleep strategy, aiming to mitigate the interference and improve the energy efficiency in heterogeneous networks. Then it’s converted into a multi-objecti

The effect of injection speed on the law of heavy oil initiation and seepage flow research

Autor: Zhu Jiajia, Liu Jing, Li Zhengbin, Jiang Yimin, Jiang Zhihao, Liu Xiujie, Zhao Zhiqiang

Publikováno v: E3S Web of Conferences, Vol 358, p 01022 (2022)

In order to make the heavy oil flow, the repulsion pressure gradient should be larger than the start-up pressure gradient. The results show that the smaller the injection speed is, the smaller the start pressure gradient is, and the subsequent seepag
