Denim fabrics are products that provide durability and ease of use, used by young people or all ages who prefer comfortable wear in daily life. In this study, the objective hand values denim with three weft yarn types (100% cotton elastane, 85% 15% Modal Tencel elastane), two twill directions (3/1 Z S), four washing processes (bleach, enzyme, rinse, stone) were investigated. For purpose, compre...

In this paper a method is demonstrated for tuning the stiffness of building blocks statically balanced compliant ortho-planar mechanisms. Three post-buckled mechanisms are proposed where flexural rigidity can be manipulated over part their length in order to tune ratio between first two critical loads. A sensitivity analysis using finite element simulation showed that best balancing performance...

This paper aims at demonstrating the feasibility of Glass Fiber Reinforced Polymer (GFRP) systems for low-profile bypass roadways, in particular, sandwich panels comprised of GFRP facings and a Fiber Reinforced Foam (FRF) core. With the purpose of investigating the performance of the sandwich construction, an experimental program, including static and dynamic fatigue tests, was performed. The s...

Themechanical behaviorof grapheneflakesunderboth tension and compression is examined using a cantilever-beam arrangement. Twodifferent sets of samples are employed.One consists of flakes just supported on a plastic bar. The other consists of flakesembeddedwithin theplastic substrate.Bymonitoring the shift of the 2DRaman linewith strain, information on the stress transfer efficiency as a functio...

When microcantilevers are used in the dynamic mode, the resonance shift uponmaterial adsorption depends on the position of the adsorbate along the microcantilever. Wehave previously described that the adsorbate stiffness needs to be considered in addition toits mass in order to correctly interpret the resonance shift. Here we describe a method thatallows obtaining the Young's modulus of the ads...

The mechanical properties of biopolymers can be determined from a statistical analysis of the ensemble of shapes they exhibit when subjected to thermal forces. In practice, extracting information from fluorescence microscopy images can be challenging due to low signal/noise ratios and other artifacts. To address these issues, we develop a suite of tools for image processing and spectral data an...
