Reinforcement placement on mechanics and deformation of stepped reinforced retaining wall experimental study of characteristics

Autor: Zhu Yalin, Chen Renyi, Wu Liming, Xu Qian, Zhan Zijian

Publikováno v: Applied Rheology, Vol 32, Iss 1, Pp 155-165 (2022)

Three sets of indoor model tests of reinforced retaining walls were conducted to study the effects of reinforcing material placement on the displacement of reinforced retaining walls, wall top settlement, earth pressure distribution, and potential fa

Low Spin-Axis Variations of Circumbinary Planets

Autor: Chen, Renyi, Li, Gongjie, Tao, Molei

Having a massive moon has been considered as a primary mechanism for stabilized planetary obliquity, an example of which being our Earth. This is, however, not always consistent with the exoplanetary cases. This article details the discovery of an al

GRIT: a package for structure-preserving simulations of gravitationally interacting rigid-bodies

Autor: Chen, Renyi, Li, Gongjie, Tao, Molei

Spin-orbit coupling of planetary systems plays an important role in the dynamics and habitability of planets. However, symplectic integrators that can accurately simulate not only how orbit affects spin but also how spin affects orbit have not been c

Data-driven Prediction of General Hamiltonian Dynamics via Learning Exactly-Symplectic Maps

Autor: Chen, Renyi, Tao, Molei

We consider the learning and prediction of nonlinear time series generated by a latent symplectic map. A special case is (not necessarily separable) Hamiltonian systems, whose solution flows give such symplectic maps. For this special case, both gene
