WebThe maximum shear stress created in a solid round bar subject to impact is given by the equation: where U = change in kinetic energy; G = shear modulus; V = volume of rod; and U = Urotating + Uapplied; Urotating = 1 2 Iω2; Uapplied = Tθdisplaced; I = mass moment of inertia; ω = angular speed. Shear stress in fluids [ edit] WebIntracranial aneurysms are abnormal focal dilations of the brain arteries.They are commonly found near the arterial bifurcations in the Circle of Willis[1].The occurrence rate of intracranial aneurysm is about 5% in the population.As the aneurysm swells, the weakened part may rupture, causing intracranial hemorrhage and high mortality rate[2].
