Abstract
The rectangular orthotropic strip under flexure is studied by decomposing the problem into an interior (St. Venant) problem and a boundary problem. The bound¬ary problem is solved via eigenfunction expansion under the assumption of transverse inextensibility. It is shown that logarithmic stress singularities are present at the corners of the clamped end section and the corresponding stress-intensity factor is computed.File in questo prodotto:
