Determine stress concentration factors K and K for ellipsoidal holes An ellipsoidal hole of major radius a and minor radius b is oriented at an angle relative to the loading direction in a solid bar of width w, length L, and thickness t. The bar is made of AISI 1095 hot-rolled (HR) steel and subjected to an axial force F as shown below. W 2a 26 0 F L (a) Use any finite element software package (such as Fusion 360, SolidWorks, or etc.) and determine the stress concentration factor K, as a function of the orientation angle 0 for three different aspect ratios: a/b = 1, a/b = 0.5 and a/b = 2.0. Consider = 0, 10, 20, 30, 40, 50, 60, 70, 80, 90 for a/b 1. Discuss your findings. Include images of the von Mise's stress/deformation fields around the hole. [Hint: Steps involved: (i) create the geometries, (ii) apply load F with the maximum stress in the bar no higher than the yield strength of the material, (iii) for each ge- ometry, locate the critical stress location and determine the difference between the maximum stress at the hole edge and the stress far from the hole, and (iv) plot the difforongo of K for differnan aboioon of ath and 21
