Abstract :
the paper presents an approach to the stress-strain and buckling analysis in fiberglass cylindrical and conical panels reinforced from the concave side with an orthogonal grid of stiffeners. a mathematical model of the timoshenko (mindlin–reissner) type is used. transverse shears and geometric nonlinearity are taken into account. the stiffeners are introduced in two ways: using the method of refined discrete introduction and the method of structural anisotropy. we use a computational algorithm based on the ritz method and the best parameter continuation method. we also provide buckling load values and make a comparison between two types of approaches to account for stiffeners, which shows good convergence.
