Nonstandard tests are necessary for analyses and verification of new developed structural and technological solutions with application of composite materials. One of the most critical primary structural parts of a typical aerospace structure is T-joint. This structural element is loaded mainly in shear, bending, peel and tension. The paper is focused on the shear loading simulations. The aim of...

UNLABELLED Evaluation of patient's response to chemotherapeutic drugs is often difficult and time consuming. Skin punch biopsies are easily accessible material that can be used for the evaluation of surrogate biomarkers of a patient's response to a drug. In this study, we hypothesized that assessment of phosphorylated histone H3 in human skin punch biopsies could be used as a pharmacodynamics b...

There are changes afoot in the way that US granting agencies, most notably the NIH, evaluate proposals. Change can be a good thing, and it is probably high time that the NIH reassessed how grants are evaluated. Frankly, I was becoming blasé about the entire granting process. It seemed that once I became inured to the low probability of funding, competition from the mega-labs, and the shift towa...

Digital punch cutting is today’s font technology. There are three different methods available for getting alphabets into digital form : hand-digitizing, auto-tracing and direct design on a workstation screen. The advent of intelligent font scaling requires us to ensure the ‘optical’ quality of a font and also the ‘numerical’ quality of its data; this, in turn, means that new procedures have to ...

laboratory data, which relate the liquefaction resistance of firoozkooh sand and non-plastic silt mixtures to shear wave velocity are presented and compared to liquefaction criteria derived from seismic field measurements by andrus and stokoe [1]. in the work described herein, cyclic triaxial and resonant column tests were conducted on specimens of clean sand and sand-silt mixtures with silt co...

Abstract The small punch test (SPT) was developed for situations where source material is scarce, costly or otherwise difficult to acquire, and has been used assessing components with variable, location-dependent properties. Although lacking standardization, the SPT employed assess properties verified using traditional testing. Several methods exist equating results stress–strain data. There ar...

The anisotropic hyperelastic model (MAT_249) and Non-Orthogonal Model (MAT_293) are the material models developed recently to simulate forming process of dry fabric fabric-reinforced thermoplastic prepregs. In this study, prediction capabilities these two in terms shear angle distribution boundary profile deformed compared over a hemispherical simulation plain weave E-glass reinforcement. Accor...

Liquid jet injections have been performed on human skin in vivo and silicone rubber using Intraject needle-free injectors. The discharge characteristics of the liquid jet were measured using a custom-built test instrument. The experiments reveal that a high-speed liquid jet penetrates a soft solid by the formation and opening of a planar crack. The fluid stagnation pressure required for skin pe...
