Fiber-Reinforced Polymer (FRP) in the form of thin-walled plate structures are widely used in different engineering applications due to their outstanding features such as: high strength-to-weight ratio, excellent fatigue and corrosion resistance, etc. This study focuses on the local buckling resistance of pultruded FRP columns by experimental work. The test data were compared to current theoretical and numerical predictions.

The objective of this study was to determine the influence of loading frequency on the failure of articular cartilage-on-bone specimens under three-point bending. Methods: In this study, cyclic three-point bending was used to introduce failure into cartilage-on-bone specimens at varying loading frequencies.

Individuals with cancer have reduced quality of life, functionality, range of motion, strength, and an increase in pain and fatigue. Exergaming appears to be an effective rehabilitation tool for Parkinson’s disease, multiple sclerosis and post-stroke patients to improve functionality, balance and quality of life.

A review of some recent data from multiaxial fatigue data from different notched materials is carried out in the paper. The approach based on the strain energy density (SED) averaged over a control volume is first used to summarise uniaxial and multiaxial fatigue strength data of welded joints made of structural steel and aluminium alloys.

The main parameters of this device are calculated from the ratio of shear stress and normal stress at the fatigue of the asphalt concrete according to the Mohr-Coulomb failure criterion. Test results with asphalt specimens show that the device is stable, the acting vertical loads were smaller and more stable.

Weld toe improvement methods have been widely investigated and have, in most cases, been found to give substantial increases in fatigue strength. However, there are large variations in the actual improvements achieved, and the results obtained by various methods are not always ranked in a consistent manner. One explanation for the observed varia tions is the lack of standardization of the optimum method of application, but variations in the material, type of loading and type of weld detail may also have influenced the results.

After 40 the muscle fibbers shrink and replaced slowly with a tough fibrous tissue.Muscle changes often begin in the 40s in women. Lipofuscin (an age-related pigment) and fat are deposited in muscle tissue. This is most noticeable in the hands, which may appear thin and bony. Muscles may become rigid with age and may lose tone, even with regular exercise. Loss of muscle mass reduces strength which contributes to fatigue, weakness, and reduced activity tolerance. Exercise is one of the best ways to slow or prevent problems with the muscles, joints, and bones....
