Uniaxial loading of the red-cell membrane

Journal of Biomechanics, 1972
Abstract The overall strain in the direction of flow of human red blood cells which adhere to a glass surface is measured for a fluid shear stress at the surface between 1 and 10 dyn/cm 2 . At a given shear stress, the overall strain depends on the width of attachment of the cell at the leading (upstream) edge and the strain increases with decreasing

Stability of Quasiequilibrium Cracks under Uniaxial Loading

Physical Review Letters, 1996
We propose a linear stability analysis of a straight crack subjected to uniaxial loading. We argue that, under quasistatic extension conditions, the crack propagation follows a straight path until the creation of a “physical” shear stress at its tip. This instability leads to a deviation of the fracture from the direction perpendicular to the applied ...

Effective widths of plates loaded uniaxially

Thin-Walled Structures, 1983
Abstract An approximate method for the analysis of axially loaded plates with initial imperfections is presented. Formulae for the computation of effective widths of rectangular plates having nine different combinations of boundary conditions have been derived using the energy method; all the boundary edges are constrained to remain straight in-plane,

Ratchetting of porcine skin under uniaxial cyclic loading

Journal of the Mechanical Behavior of Biomedical Materials, 2011
Skin soft tissue (e.g., porcine skin) was tested in vitro under uniaxial cyclic loading, and its biomechanical responses were investigated to realize some basic properties which are very significant in assessing the fatigue life of skin soft tissue. The results show that a cyclic accumulation of peak and valley strain, which can be terminologically ...

Uniaxial loading of orthotropic materials.

AIAA Journal, 1968
A method is presented for correlation of elasticity measurements made in variously oriented tensile tests of anisotropic materials. Linear relationships are established between each measured quantity and a trigonometric function of the orientation. A set of test data for carbon phenolic, exhibiting typically large scatter which precludes direct curve ...

Ultrasonic properties of random media under uniaxial loading

The Journal of the Acoustical Society of America, 2001
Acoustic properties of two types of soft tissue-like media were measured as a function of compressive strain. Samples were subjected to uniaxial strains up to 40% along the axis of the transducer beam. Measurements were analyzed to test a common assumption made when using pulse-echo waveforms to track motion in soft tissues—that local properties of ...

Influences of uniaxial loads on local resonances in rails

ASNT Research Symposium 2023 Proceedings, 2023
The deficiency of rail stress management in continuous welded rails could lead to rail buckling or pull-apart, which can seriously jeopardize rail safety. Federal Rail Administration (FRA) safety report indicates “track alignment irregularities (buckled/sun kink)” is one of the leading causes within the track-related category for rail accidents [1 ...

The Biomechanical Response of Spinal Cord Tissue to Uniaxial Loading

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2006
The spinal cord is an integral component of the spinal column and is prone to physical injury during trauma or more long-term pathological insults. The development of computational models to simulate the cord-column interaction during trauma is important in developing a proper understanding of the injury mechanism.

Modelling the Mechanical Response of Adobe Components under Uniaxial Loading

Key Engineering Materials, 2018
This paper presents a constitutive relationship to describe the uniaxial response in statics of brick and mortar samples of Adobe, a traditional masonry whose components are made of sundried soil mixture reinforced with fibres. Only recently Adobe has been attracting scientific attention, primarily as a consequence of the dramatic failures these ...

Application of a Theory of Viscoplasticity to Uniaxial Cyclic Loading

Journal of Engineering Materials and Technology, 1983
The uniaxial specialization of a theory of cyclic viscoplasticity is described. The theory incorporates a realistic description of nonlinear stress-strain curves and of transient cyclic hardening and softening in both rate-dependent and rate-independent approximations.
