Timoshenko beam formulation for in-plane behaviour of tapered monosymmetric I-beams: Analytical solution and exact stiffness matrix

, 2021
The presence of curved centroidal axis in tapered monosymmetric I-beams results in coupling between the axial and flexural behaviours. In this paper, an extended Timoshenko beam formulation that incorporates the axial–flexure coupling in the governing ...

Injectable AuNP-HA matrix with localized stiffness enhances the formation of gap junction in engrafted human induced pluripotent stem cell-derived cardiomyocytes and promotes cardiac repair.

Biomaterials, 2021
Cell therapy offers a promising paradigm for heart tissue regeneration. Human induced pluripotent stem cells (hiPS) and their cardiac derivatives are emerging as a novel treatment for post-myocardial infarction repair. However, the immature phenotype and

Simultaneous toughness and stiffness of 3D printed nano-reinforced polylactide matrix with complete stereo-complexation via hierarchical crystallinity and reactivity.

International Journal of Biological Macromolecules, 2022
A novel strategy adaptive to 3D printing of stereo-complexed polylactide matrix for simultaneous toughness and stiffness was designed. Stereo-complexation is a potent way to enhance both aqueous stability and heat resistance of polylactide, but also ...

Coupled bending-torsional dynamic stiffness matrix for timoshenko beam elements

Computers & Structures, 1992
Abstract Analytical expressions for the coupled bending-torsional dynamic stiffness matrix elements of a uniform Timoshenko beam element are derived in an exact sense by solving the governing differential equations of motion of the element. Application of the developed theory in the context of wings, blades and grillages is discussed with particular ...

Multirate Haptic Rendering Using Local Stiffness Matrix for Stable and Transparent Simulation Involving Interaction With Deformable Objects

IEEE transactions on industrial electronics (1982. Print), 2020
Simulation involving interaction with deformable objects often causes stability problems because a slowly updated force generates additional energy to the human user.

Coupled bending–torsional dynamic stiffness matrix for axially loaded beam elements

International Journal for Numerical Methods in Engineering, 1992
AbstractAnalytical expressions for the coupled bending–torsional dynamic stiffness matrix elements of an axially loaded uniform beam element are derived in an exact sense by solving the governing differential equations of motion of the beam. The influence of axial force on the coupled bending–torsional frequencies of a cantilever and hinged–hinged beam

STRUCTURAL ANALYSIS OF MULTISTORY BUILDING USING COUPLED BEM-STIFFNESS MATRIX

Proceedings of the 4th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2013), 2014
This paper presents a structural analysis scheme for multistory buildings. In this analysis the boundary element method (BEM) is used to derive the stiffness. Such a matrix is coupled with the vertical skeletal elements using the traditional assembly procedures.

Coupled bending-torsional dynamic stiffness matrix of an axially loaded timoshenko beam element

International Journal of Solids and Structures, 1994
Explicit expressions for dynamic stiffness matrix of an axially loaded, bending-torsion coupled beam with the effects of rotatory inertia and shear deformation are presented. The inversion of the \(6\times 6\) algebraic matrix and its following multiplication are performed by the symbolic computing package REDUCE.
