This paper deals buckling behavior of laminated composite cylindrical shells subjected to combination of axial compression and torison. Linear and nonlinear finite element analysis are carried out . the influence of load type, load ratio, fiber orientation angle, stacking sequence, and intial imperfect on buckling behavior is discussed.

The molecular structure of (+)-6-Me hoxy-.alpha.-methyl-2-naphthaleneacetic acid (Naproxen), $C_{14}H_{14}O_{ 3}$, was determined by X-Ray diffraction technique. Naproxen crystallized in $P2_1$ with two molecules on the unit cell of dimensions a = 7.855, b = 5.783, c = 13.347$\AA$ and $\beta$ = $93.9^{\circ}$
