However, the inspiratory muscles received less attention in terms of studies regarding its effects on athletic performance. The inspiratory muscles are muscles involved in the breathing mechanism. These muscles include the diaphragm, intercostal muscles, levatores costorum and the serratus posterior superior (Palastanga and Soames, 2012). However, there are other muscles that assist in increasing the thoracic dimensions in the case of extreme respiratory distress in an attempt to draw more air into
several load cases. (With specific distribution and magnitude) The load considered in the present analysis is one of the critical load cases for the wing. During flight the wings will deflect in the upward direction. Due to this loading, bottom skin of the wing will experience tension and top skin will be under compression. The stiffened panel considered for the analysis is the bottom skin and has a big landing gear cutout. Essentially the bottom stiffened panel experiences tension-tension loading.
