Abstract: Natural frequencies and corresponding modal forms for thin‐walled bars of constant and open cross section are examined using the finite element method. Following the classical thin‐walled bar theory, warping and Saint‐Venant ...

Abstract: Instability of thin walled bars of variable, open cross sections is analyzed. A thin walled bar is treated as a special case of the membrane shell with the internal constraints (Vlasov's and Wagner's assumptions). The ...

Abstract: An application of the finite element method to the theory of thin‐walled bars of variable, open cross section is presented. A thin‐walled bar is considered as a special case of the membrane shell with internal constraints ...

Abstract: Analysis of rectangular plates resting on a Winkler-type, one-parameter foundation is studied. The finite element method is applied and a 12-degree-of-freedom, nonconforming rectangular plate element is adopted. Based on ...

Abstract: Improvement in impact simulation between vehicles and roadside safety hardware is investigated. The use DYNA3D, a nonlinear, explicit, three‐dimensional, public‐domain, finite‐element code for vehicle impact numerical ...
