In this article a practical mass-spring system was developed to simulate the draping of woven and knitted fabrics. The material properties important to fabric drape, including aerial density, tensile, shear, and bending properties were measured using the Kawabata Evaluation System and the experimental data were incorporated into the mass-spring model to simulate the dynamic draping behavior of ...

Deep-draw experiments are performed on both glass and carbon fabric to better understand the origin of wrinkle growth during complex forming assess accuracy, robustness computational cost simulations engineering fabrics. During experiments, shape deformed blanks is digitised using two different non-contact measurement techniques (Structured Light Scanning Photogrammetry). The resulting digital ...

Chemical clocks are often used as exciting classroom experiments, where an induction time is followed by rapidly changing colours that expose oscillating concentration patterns. This type of reaction belongs to a class of nonlinear chemical kinetics also linked to chaos, wave propagation and Turing patterns. Despite its vastness in occurrence and applicability, the clock reaction is only well u...

In this study, I consider the ground motions generated by 11 moderate (Mw 4.0–5.6) earthquakes in the central and eastern United States that are thought or suspected to be induced by fluid injection. Using spatially rich intensity data from the U.S. Geological Survey “Did You Feel It?” system, I show the distance decay of intensities for all events is consistent with that observed for tectonic ...

Keywords: A. Fabrics/textiles B. Mechanical properties C. Finite element analysis (FEA) D. Mechanical testing a b s t r a c t A method of combining 1-d and 2-d structural finite elements to capture the fundamental mechanical properties of engineering fabrics subject to finite strains is introduced. A mutually constrained pantographic beam & membrane mesh is presented and simple homogenisation t...

Samples of fault gouge from the San Andreas Fault drill hole (SAFOD), a shale from the North Sea sedimentary basin and schists from metamorphic rocks in the Alps have been analyzed with high energy synchrotron X-rays to determine preferred orientation of mica and clay minerals. The method relies on obtaining 2D diffraction images which are then processed with the crystallographic Rietveld metho...
