Anomalous frozen evanescent phonons [PDF]
Nature CommunicationsEvanescent Bloch waves are eigensolutions of spatially periodic problems for complex-valued wavenumbers at finite frequencies, corresponding to solutions that oscillate in time and space and that exponentially decay in space.

A study on the macro- and micro-dynamic characteristics of lumbar spine under different frequencies based on finite element analysis [PDF]
Scientific ReportsWhole-body vibration is a critical occupational hazard linked to spinal degeneration, yet the multi-scale biomechanical mechanisms underlying vibration-induced damage remain poorly understood.

Goal oriented error estimation in multi-scale shell element finite element problems
Advanced Modeling and Simulation in Engineering Sciences, 2021 A major challenge with modern aircraft design is the occurrence of structural features of varied length scales. Structural stiffness can be accurately represented using homogenisation, however aspects such as the onset of failure may require information ...

Two-dimensional beams in rectangular coordinates using the radial point interpolation method
REM: International Engineering Journal, 2019 The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational

Saint-Venants principle and the plane elastic wedge [PDF]
International Journal of Solids and Structures, 1999 The stress field due to self-equilibrating loading on the inner or outer arc of a plane strain elastic wedge sector is affected by two agencies: a geometric effect of increasing or decreasing area, and decay as anticipated by Saint-Venants principle (SVP) .

Elastic Stresses in Thin-Walled Torsional Structures Designed with SADSF Method
Engineering Transactions, 2014 The paper presents general conclusions arising from FEM analyses of elastic properties of thin-walled structures designed with the application version of the statically admissible discontinuous stress fields (SADSF) method. The analyses have been carried

Archive for Rational Mechanics and Analysis, 1965 The principle of the elastic equivalence of statically equivalent systems of load, or Saint-Venant's Principle, is given a precise mathematical formulation and proof. Counterexamples to traditional verbal statements of the principle are given, and the results are compared with previous mathematical work on the Saint-Venant principle.
