Elastic buckling stresses of rectangular plates subjected to in-plane loads are generally calculated as eigenvalue problems to get their accurate solutions. The elastic buckling stresses have to be evaluated when thin-walled structures such as ships and offshore structures are designed. Since it is difficult for structural designers to frequently use numerical methods to get the accurate values, they usually use simple equations or charts generated from the numerical way. However the buckling stresses obtained from the equations and charts are sometimes inaccurate. This paper describes a method that the designers can remotely use the numerical way through Internet technology. The designer can know accurate buckling stress values using the system developed in this study. For example, they can immediately get elastic buckling^stresses of the rectangular plates on Internet web browsers after they input minimum number of parameters.
