Mechanical Engineering Journal, 2016 In s-version finite element method (s-FEM) proposed by Fish (1992), a local mesh that represents the local feature such as a hole or a crack is superposed on a global mesh that represents the shape of the whole analysis model.

Coupled axial-bending dynamic stiffness matrix for beam elements
Computers and Structures, 2019 The dynamic stiffness matrix for beams which exhibit coupling between axial and bending deformations is developed from first principle so that their free vibration analysis can be carried out in an accurate and efficient manner. The coupling between the axial and bending motion essentially arises due to non-coincident centroid and shear centre of the ...

Coupled axial-bending dynamic stiffness matrix and its applications for a Timoshenko beam with mass and elastic axes eccentricity [PDF]
Thin-Walled Structures, 2021 The dynamic stiffness matrix of a coupled axial-bending Timoshenko beam is developed to investigate the free vibration behaviour of such beams and their assemblies. Applying Hamilton's principle, the governing differential equations of motion of a Timoshenko beam in free vibration is derived by considering the axial-bending coupling effect arising from

Exact Stiffness Matrix for Nonprismatic Beams with Parabolic Varying Depth
Journal of Engineering, 2023 In this paper, an exact stiffness matrix and fixed-end load vector for nonprismatic beams having parabolic varying depth are derived. The principle of strain energy is used in the derivation of the stiffness matrix. The effect of both shear deformation

Quarterly Report of RTRI (Railway Technical Research Institute) (Japan), 2008 Railway structures are often built near active faults in the Japanese Archipelago. In order to improve the safety of trains running on railway structures, therefore, it is important to predict earthquake ground motion taking into account the effect of such faults.

The eigenscrew decomposition of spatial stiffness matrices
IEEE Transactions on Automation Science and Engineering, 2000 A manipulator system is modeled as a kinematically unconstrained rigid body suspended by elastic devices. The structure of spatial stiffness is investigated by evaluating the stiffness matrix “primitives”-the rank-1 matrices that compose a spatial ...

PKM2 mediates the glycolytic response to matrix stiffness in lung fibroblasts [PDF]
Frontiers in Cell and Developmental BiologyIntroductionMatrix stiffening during idiopathic pulmonary fibrosis (IPF) creates a mechanically altered microenvironment that promotes fibroblast activation, yet the metabolic consequences of these mechanical cues remain incompletely defined.
