We present analytical solutions of the electrostatically actuated initially deformed cantilever beam problem. We use a continuous Euler-Bernoulli beam model combined with a single-mode Galerkin approximation. We derive simple analytical expressions for two commonly observed deformed beams configurations: the ...
The aim of this study is to develop a simplified natural fundamental frequency formula for the post-tensioned balanced cantilever bridges using the Operational Modal and Finite Element Analyses results. For this purpose, experimental and numerical studies were carried out on the five post-tensioned bal...
Studies on the Accuracy of the Results Predicted by the Simple Beam Theory in the case of Short Cantilever Beams The simple beam theory can predict the deflection of the loaded end of cantilever beams with a high level of accuracy if the length-to-diameter ratios for the beams are high. He...
Based on the finite element method, a model of a double cantilever beam is established to verify the accuracy of the formula through comparison with the experimental results. Results The results show that there must be at least four cohesive elements in a cohesive zone length to describe the ...
