    STUDY ON MECHANICAL PROPERTIES OF POROUS STRUCTURES BASED ON TPMS by WANG MaoHua, DUAN MingDe, YANG ZiWei, ZHANG ZhuangYa, WANG Pei, HAN ZongZheng

    Published 2022-01-01
    “…Finite element analysis and experimental results show that with the increase of distance function k, the elastic modulus and yield strength of the P unit porous scaffold presented an increasing trend, However, the elastic modulus and yield strength of the FRD unit porous scaffold showed a downward trend, Moreover, Comparing to FRD unit, P unit porous scaffolds were more likely to be crushing, through the control of the TPMS types and the distance function k value, the porosity, elastic modulus and yield strength of the porous scaffold can be effectively adjusted. The results provide a basis for the design of tissue-engineered bone scaffolds.…”

    ANALYSIS OF THE CONSTRAINT EFFECT AND CREEP CRACK INITIATION TIME FOR STRUCTURE WITH ЕMBEDDED CRACKS by LI YuPeng, LI WenPeng, LI DingHe, WU DongQuan, WANG YuFeng, ZHENG YuXiang

    Published 2024-04-01
    “…Besides, for the creep crack initiation times, the structure with a larger <italic>a</italic>/<italic>t</italic> or <italic>a</italic>/<italic>c</italic> or loadings would accompany high crack driving force under creep condition, which could cause a shorter period to creep cracking initiation, as well as a smaller creep crack initiation time. …”

    Effect of Al2O3, MgO, and CuOx on the dissolution behavior of rhodium in the Na2O-SiO2 slags by Wiraseranee C., Yoshikawa T., Okabe T.H., Morita K.

    Published 2013-01-01
    “…The dissolution of rhodium in slags was suppressed by the addition of Al2O3 and MgO, where Al2O3 behaved as an acidic oxide and MgO behaved as a diluent of slag basicity at a fixed Na2O/SiO2 ratio of 0.97. The content of copper in solid rhodium equilibrated with the CuOx bearing slags slightly increased with increasing content of CuOx, and CuOx was found to slightly enhance the dissolution of rhodium. …”
