EAS4200C Aerospace Structures Homework #4 (Due: Oct. 2nd) 1. Show that there is no warping in the bar of circular cross-section Hint: First, calculate the constant C in 22 (, ) 1 xy C aa φ ⎛⎞ =+ ⎝⎠ from the compatibility equation. Second, calculate shear strains γ xz and γ yz from shear stresses τ xz and τ yz . Third, integrate w ( x , y ) from the definition of shear strains: , xz yz wu wv xz yz γγ ∂∂ . 2. Consider a straight bar of a uniform elliptical cross-section. The semimajor and semiminor axes are a and b , respectively. (a) Show that the stress function of the following form:
