    GEOLOGICAL CONSEQUENCES OF AMORPHIZATION OF THE LITHOSPHERE AND UPPER MANTLE STRUCTURES CAUSED BY HYDROGEN DEGASSING by Iosif L. Gufeld

    Published 2015-10-01
    “…Due to combinations of these impacts, principally new conditions are established, in which  amorphized/irregular and regular structures are formed. Such a twophase system, including a variable number of regular/crystalline and irregular/amorphized phases, may be responsible for specific and unique spatial geological structures, such as the Moho, blocks and ‘subduction’ zones, and variations of their parameters. …”

    Statistical Identification of Parameters for Damaged FGM Structures with Material Uncertainties in Thermal Environment by Yalan Xu, Yu Qian, Kongming Guo

    Published 2018-01-01
    “…In order to implement the forward propagation of uncertainties required in the stochastic model updating and avoid large error resulting in the nonconvergence of the iteration process, an algorithm is proposed to compute the covariance between the modal parameters and the identified parameters for damaged FGM structures. The proposed method is illustrated by a numerically simulated damaged FGM beam with continuous spatial variation of material properties and verified by comparing with the Monte-Carlo simulation (MCS) method. …”
