Measurement of short span stress-strain curves of paper

Nordic Pulp & Paper Research Journal, 2003
A new method is reported for measuring the short span stress-strain curve of paper using a zero/short span tester with additional instrumentation to measure load and displacement during a test. The method is to subtract the zero-span displacement-load curve from the short-span displacement-load curve, so as to obtain the displacement-load curve of the ...

Compression stress-strain curve of rammed earth: Measuring and modelling

Results in Engineering, 2023
This research article is about a study on the mechanical behavior of rammed earth under compression stress. The main purpose is to establish a simple stress-strain model for rammed earth. The tested rammed earthen materials are made of various local materials with different grain-size curves and grain shapes.

Measurement of Strain-Amplitude Dependent Internal Friction with Torsion Pendulum and Vibration Reed Methods [PDF]

Materials Research, 2018
In the traditional standard of internal friction measurement the torsion pendulum and vibration reed were preferentially recommended where the issue of strain amplitude dependence of internal friction was not concerned.

Young-Measure approximations for elastodynamics with non-monotone stress-strain relations [PDF]

ESAIM: Mathematical Modelling and Numerical Analysis, 2004
Summary: Microstructures in phase-transitions of alloys are modeled by the energy minimization of a nonconvex energy density \(\phi\). Their time-evolution leads to a nonlinear wave equation \(u_{tt}=\text{div}\;S(Du)\) with the non-monotone stress-strain relation \(S=D\phi\) plus proper boundary and initial conditions. This hyperbolic-elliptic initial-

Synchrotron strain scanning for residual stress measurement in cold-drawn steel rods [PDF]

, 2011
Cold-drawn steel rods and wires retain significant residual stresses as a consequence of the manufacturing process. These residual stresses are known to be detrimental for the mechanical properties of the wires and their durability in aggressive ...

Direct Stress-Strain Measurements from Bulged Membranes Using Topography Image Correlation [PDF]

Experimental Mechanics, 2014
This paper discusses an experimental method to characterize thin films as they are encountered in microelectronic devices. The method enables the measurement of the stress and strain of pressure deflected bulged membranes without using a priori defined bulge equations.
