A technique is presented for the constructions of stressstrain relations based on experimental, cyclic, damping data. The extension of this technique to the biaxial stress case is then shown followed by an example application involving flexural vibrations of a cantilever.

An inverse analyses procedure for determining the mechanical material properties of strain hardening cement-based materials is presented. It allows to determine the uniaxial stressstrain curve up to the material’s localization point on the basis of the results of four-point bending tests. In these tests, the beam curvature is measured and serves as input value for the inverse analysis. An evolu...

We propose a simple coarse-grained lattice model for liquid crystal elastomers and show, through large scale Monte Carlo simulations, that it can reproduce stressstrain, order, light transmission, and other experiments, including temperature effects. We focus both on homogeneously and inhomogeneously crosslinked materials.

A Rouse model for polymer chains is incorporated into the linear continuous stickslip molecular-based tube reptation ideas of Doi-Edwards and Johnson-Stacer. This treats the physically constrained (PC) molecular stretches as internal strain variables for the overall PC/chemically cross-linked (CC) system. It yields an explicit system of stress-strain equations for the system permitting simple c...

An odontogenic keratocyst was detected and treated in the lower jaw. A 3D reconstruction from a CT scan was made before surgery and 15 months after. The healing process was monitored using stressstrain analyses of the mandible with a system of keratocysts, and by comparing them with the analogous data of stress-strain analyses of the patients mandible after the surgical extirpation of the cysts.

Medical textiles are widely used as bandages for diverse purposes. Usually textiles have a certain stiffness depending on the passive material and the manufacturing technique. To improve and extend the applications by making the stressstrain characteristic adaptive, hybrid structures made of textile with integrated shape memory alloys (SMA) are investigated and evaluated regarding its capabilit...

In this paper, effects of critical parameters, namely initial gap, squeezing speed and applied current were statistically investigated on the mechanical behaviour of MR fluid in squeeze mode. A set of 17 experiments was designed using Design Expert 7 software to gather data from response surface methodology (RSM). The responses in terms of compression modulus were then calculated. An MRF132-DG ...

The current paper is focussed on the nodular cast iron ASTM 80-55-06 (EN-GJS-600). The individual microstructure was investigated by light and scanning electron microscopy as well as micro-hardness measurements. Stress-controlled fatigue tests were performed at ambient temperature with testing frequencies of f = 5 Hz and f = 150 Hz. The cyclic deformation behaviour was characterised by means of...

For the design of steel and concrete structures, most modern international design codes allow the use of plastic stressstrain-diagrams for the analysis of the bending resistance of the cross-section in the ultimate limit state. Curiously, in Europe and most other parts of the world, timber structures are still designed for the ultimate limit state with the old, conservative concept of full elas...

Numerical methods provide a new way for solving complex geotechnical engineering problems. Firstly, we review the emergence and development of numerical methods, introduce basic principles particle flow discrete element its application in engineering. After that, method servo combination cylinder loading plate is used, simulation three-dimensional rock triaxial unloading test carried out by PFC...
