International Journal of Energy Research, Volume 2025, Issue 1, 2025.Coal mining will lead to rock strata bending deformation and the redistribution of stress field. The change of principal stress magnitude and direction will influence the failure zone distribution of the coal pillar, which determines the stability and safety of roadway near goaf. In this paper, a theoretical model is established to analyze the rotation

Vibration Analysis of a Pipeline System Based on Model Truncation
Shock and Vibration, Volume 2025, Issue 1, 2025.Designing a complex pipeline for a floating production storage and offloading (FPSO), particularly over long distances, presents significant challenges in vibration analysis. Traditional modeling methods, which often assume finite lengths and simple configurations, fall short as they do not account for the integrality and locality of long spans and the

Shock and Vibration, Volume 2025, Issue 1, 2025.Considering the thermal environment of rotating blades, this paper calculated the predeformation caused by thermal strain and centrifugal strain using the pseudo‐static analysis method. The finite element model of the structural dynamics of blades was constructed by applying the predeformation. Then, this paper solved the nonlinear forces acting on the

Elliptic Spline Functions and the Rayleigh-Ritz-Galerkin Method [PDF]
Mathematics of Computation, 1970 Error estimates for the Rayleigh-Ritz-Galerkin method, using finite-dimensional spline type spaces, for a class of nonlinear two-point boundary value problems are discussed. The results of this paper extend and improve recent corresponding results of B. L. Hulme, F. M. Perrin, H. S. Price, and R. S. Varga.
