    Experimental Investigation on the Energy Consumption Difference between the Dynamic Impact and the Drilling Tests of Rocks by Shoudong Xie, Mingjian Huang, Junji Lu, Wang Xi, Zhenyang Xu

    Published 2022-01-01
    “…Additionally, the EC difference was compared based on the EC required to break a single unit volume of rock. The obtained results indicate that the sensitivity of the dynamic strength of rocks with different lithologies to strain rate is different and that the higher the uniaxial compressive strength is, the more sensitive it is. …”

    In‐Situ Rheology Measurements via Machine‐Learning Enhanced Direct‐Ink‐Writing by Robert D. Weeks, Jennifer M. Ruddock, J. Daniel Berrigan, Jennifer A. Lewis, James. O. Hardin

    Published 2025-01-01
    “…Direct ink writing, an extrusion‐based 3D printing method, is well suited for high‐mix low‐volume manufacturing. However, an iterative approach, using random selection or constant expert guidance, is still used to create printable inks and optimize printing parameters by expending significant amounts of time, materials, and effort. …”

    Experimental study on improving the effect of microorganisms in solidifying fine-grained soil by red mud by Peng Liu, Yu Cheng, Guanghui Shao

    Published 2025-02-01
    “…The results show that: (1) Red mud can significantly improve the production of cement during microbial reinforcement of fine-grained soils; the optimal dosage of red mud is 20 %, which increases the strength by 34.6 % and the production of cement by 42.9 %, compared with conventional MICP. (2) After red mud was incorporated into the soil, the pore volume and pore diameter of the treated soil were significantly reduced, and the overall compactness was further improved. (3) The enhancement mechanism of microbial consolidation of fine-grained soils by red mud is mainly due to the presence of chemically active β-C2S and calcium oxide in red mud. …”

    Evolution of Dynamic Recrystallization in 5CrNiMoV Steel during Hot Forming by Zhiqiang Hu, Kaikun Wang

    Published 2020-01-01
    “…Based on the study of characteristic stresses and strains on the true stress-strain curves, a DRX kinetics model was constructed to characterize the influence of true strain, temperature, and strain rate on DRX evolution, which revealed that higher temperatures and lower strain rates had a favorable influence on improving the DRX volume fraction at the same true strain. Microstructure observations indicated that DRX was the main mechanism and austenite grains could be greatly refined by reducing the temperature of hot deformation or increasing the strain rate when complete recrystallization occurred. …”
