Analytical Stiffness Matrix for Curved Metal Wires [PDF]

open access: yesProcedia Structural Integrity, 2018
The paper presents an analytic stiffness matrix for curved thin metal wires, derived by the application of the second Castigliano’s Theorem. The matrix accounts both bending and axial stiffness contributions in plane.

Stiffness of Woven Ceramic Matrix Composites with Matrix Cracks

open access: yes40th Structures, Structural Dynamics, and Materials Conference and Exhibit, 1999
An account is given of an ongoing study aimed at the analysis of plain weave ceramic matrix woven composites (CMC) with matrix cracks. The issues important for the analysis of such composites and for a development of an analytical model of thermography ...

Matrix stiffness, endothelial dysfunction and atherosclerosis

open access: yesMolecular Biology Reports, 2022
Abstract Background Atherosclerosis (AS) is the leading cause of the human cardiovascular disease (CVDs). Endothelial dysfunction promotes the monocytes infiltration and inflammation that participate fundamentally in atherogenesis. Endothelial cells (EC) have been recognized as mechanosensitive cells and have different responses to distinct ...

Nonswelling and Hydrolytically Stable Hydrogels Uncover Cellular Mechanosensing in 3D

open access: yesAdvanced Science, 2022
While matrix stiffness regulates cell behavior on 2D substrates, recent studies using synthetic hydrogels have suggested that in 3D environments, cell behavior is primarily impacted by matrix degradability, independent of stiffness.

Three-dimensional decellularized tumor extracellular matrices with different stiffness as bioengineered tumor scaffolds

open access: yesBioactive Materials, 2021
In the three-dimensional (3D) tumor microenvironment, matrix stiffness is associated with the regulation of tumor cells behaviors. In vitro tumor models with appropriate matrix stiffness are urgently desired.

Modeling the effect of fracture orientation on porus media anisotropy using the T-matrix method [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2022
Fracture orientation is crucial in porous media anisotropy. In the current study we investigate the role of fracture orientation based on a novel Rock Physics method - the T-matrix approach. This method allows us to study the fracture porosity, shape and

Exact Solutions for Torsion and Warping of Axial-Loaded Beam-Columns Based on Matrix Stiffness Method

open access: yesNanomaterials, 2022
The typically-used element torsional stiffness GJ/L (where G is the shear modulus, J the St. Venant torsion constant, and L the element length) may severely underestimate the torsional stiffness of thin-walled nanostructural members, due to neglecting ...

Heterogeneous matrix stiffness regulates the cancer stem-like cell phenotype in hepatocellular carcinoma

open access: yesJournal of Translational Medicine, 2022
Background Solid tumors are stiffer than their surrounding normal tissues; however, their interior stiffness is not uniform. Under certain conditions, cancer cells can acquire stem-like phenotypes.
