The tension test method of strip steel on stretching winding straightener tension roll group was elaborated. The material and paster form of resistance strain foil in tension test sensor were designed. The measure circuit of tension test sensor was designed. The material and structural form of elastic body of tension test sensor were designed. Strength computation was made on elastic body of te...

We analyze the asymptotic behavior of the antiplane deformations of a fragile material reinforced by a reticulated elastic structure. The microscopic geometry of this material is described by means of two “small” parameters: the size ε of the periodic grid and the ratio δ between the thickness of each of the fibers and their period of distribution. We show that this behavior depends dramaticall...

The development of piezospectroscopic (PS) composites has enabled the creation of a non-destructive evaluation (NDE) technique which integrates piezospectroscopy, digital image correlation (DIC) and analytical multi-scale mechanics to map the elastic modulus of a coated material. The measured elastic modulus was represented as a normal distribution with a mean value (32.2 GPa) which is within 8...

BACKGROUND The use of a pneumatic tourniquet to obtain a bloodless field during a total knee arthroplasty (TKA) allows the surgeon to work with greater technical precision in a safe, clear environment. Despite the benefits of surgical tourniquets and many advances in tourniquet equipment, their use is not without risk and complications may still occur. The primary aim of this study was to deter...

Elastic rods are curve-like elastic bodies that have one dimension (length) much larger than the others (cross-section). Their elastic energy breaks down into three contributions: stretching, bending, and twisting. Stretching and bending are captured by the deformation of a space curve called the centerline, while twisting is captured by the rotation of a material frame associated to each point...

We present several results related to the instability of MoC and MoN in the B1 ~sodium chloride! structure. These compounds were proposed as potential superconductors with moderately high transition temperatures. We show that the elastic instability in B1-structure MoN, demonstrated several years ago, persists at elevated pressures, thus offering little hope of stabilizing this material without...
