DESIGN AND STRESS ANALYSIS OF AIRCRAFT WING RIB WITH VARIOUS CUT OUTS
S. Bairavi, Mr. Suresh Balaji
Abstract :
Stress concentration in an elastic body may be caused mainly by the two–mechanisms i.e., concentrated forces acting to a body and geometrical discontinuities of a body such as holes or aupt change of its surface geometry. In this paper the different geometric discontinuities taken into consideration. The local stress increase induced by stress concentration sometimes causes the initiation of a fatigue crack in a structure, which must be carefully examined for engineering design. The presence of cutouts in aircraft wing ribs creates stress concentration, which eventually reduces the mechanical strength of the structure and in extreme cases may lead to its failure. In this paper the induced stresses for ribs with circular, elliptical and rectangular cutouts have been estimated with the help of finite element software package ANSYS 14.
