    Three-Dimensional Imaging of High-Contrast Subsurface Anomalies: Composite Model-Constrained Dual-Parameter Full-Waveform Inversion for GPR by Siyuan Ding, Deshan Feng, Xun Wang, Tianxiao Yu, Shuo Liu, Mengchen Yang

    Published 2025-07-01
    “…However, full-waveform inversion (FWI) for GPR data struggles to simultaneously reconstruct high-resolution 3D images of both permittivity and conductivity models. Considering the magnitude and sensitivity disparities of the model parameters in the inversion of GPR data, this study proposes a 3D dual-parameter FWI algorithm for GPR with a composite model constraint strategy. …”

    The effect of the lamella pitch in the transverse layer on the deformability and stress distribution in a three-layer CLT panel modeled as a composite plate by M. Yu. Troshin, A. V. Turkov

    Published 2023-09-01
    “…We studied the effect of the pitch of the transverse layer in a three-layer CLT panel on the deformation and distribution of the resulting normal stresses. The model was a composite orthotropic plate. Because of the lack of a unified methodology for calculating layered materials with orthotropic properties in the layers, the studies were carried out by means of the SCAD+ computational complex using the finite element method. …”
