Local large deformation between cut-off wall and core wall on deep overburden by meshless method
Yantu gongcheng xuebao, 2023 As a significant type of dam on deep overburden, the earth core rockfill dam connects the concrete cut-off wall and soil core wall directly, and the "penetration" phenomenon with local large deformation may exist between cut-off wall and core wall due to

Motion estimation for large displacements and deformations
Scientific Reports, 2022 Abstract Large displacement optical flow is an integral part of many computer vision tasks. Variational optical flow techniques based on a coarse-to-fine scheme interpolate sparse matches and locally optimize an energy model conditioned on colour, gradient and smoothness, making them sensitive to noise in the sparse matches ...

Journal of Biomechanical Science and Engineering, 2021 Fruit tree branches are deflected with large deformation under bending loads applied owing to fruit weight and environmental burdens such as wind and snow. Stress and strain analyses in large bending deformations of tree branches can prevent tree failure.

An improved meshless method for finite deformation problem in compressible hyperelastic media
Vietnam Journal of Mechanics, 2021 Hyperelastic materials are considered as special category of elastic solid materials because of their nonlinear complicated constitutive laws. Due to large strain state, the behaviour of such materials is often considered in finite deformation analysis.
