A progressive FEA mechanical fatigue degradation model for composites was developed and implemented using a UMAT user material subroutine in Abaqus. Numerical results were compared to experimental strain field data from high frequency digital image correlation (DIC) of split disk testing pressure vessel cut outs with holes. The correctly predicted the onset evolution damage matrix as well fiber...
Background: Werding-Hoffmann disease is a degenerative disease of motor neurons that begins in fetus and continues to be progressive in infancy and childhood. Most of them die by 2 years of age because of respiratory failure. The simplest and most accurate method of diagnosis is detection of serum genetic marker of SMA. Case report: In this article a neonate with Werding-Hoffmann disease is...
in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...
Introduction: Myopathy and rhabdomyolysis are not common in children and, if not detected and do not treated it will be associated with high mortality and morbidity rate. The causes of rhabdomyolysis include hypokalemia, trauma, viral myositis, poisoning, rheumatoid diseases, and metabolic myopathies. Rhabdomyolysis treatment includes rapid supportive care and treatment of the underlying dise...
In many life-testing and reliability studies, the experimenter might not always obtain complete information on failure times for all experimental units. One of the most common censoring schemes is progressive type-II censoring. The aim of this paper is characterizing the parent distributions based on Shannon entropy of progressive type-II censored order statistics. It is shown that the equality...
