Abstract Fatigue of filament wound materials was investigated using Digital Image Correlation DIC monitoring every 50 th cycle a high fatigue test split disk ring sample. The cut from glass fiber reinforced polymer pressure vessel and had hole. strain field redistributed over time, lowering moving concentrations. redistributive behavior most extensive in areas that later developed local failure...

AIM To determine ocular, sudomotor, and vasomotor components of Horner's syndrome resulting from complete unilateral intraoperative damage to the parasellar sympathetic fibers during cavernous sinus surgery. METHODS Complete damage to the parasellar sympathetic fibers was found in four patients operated for central skull base lesions. Pupilometry, eyelid fissure measurement, Hertel's exophtha...

background: exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular dna results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. since ionizing radia...

The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...

Nanoscale biological fibers, such as collagen, keratin or elastin, serve as building blocks for a wide variety of biological tissues (for example, bone, skin and hair). As such, the elasticity, strength and damage tolerance of these fibers largely control the mechanical performance of tissues at the macroscale. While there is a large body of experimental data for tests on whole biological tissu...

Asbestos amosite fibers were investigated to evaluate the damage caused by a transmission electron microscope (TEM) electron beam. Since elemental x-ray intensity ratios obtained by energy dispersive x-ray spectroscopy (EDS) are commonly used for asbestos identification, the impact of beam damage on these ratios was evaluated. It was determined that the magnesium/silicon ratio best represented ...
