After investigating the beams with simple cross sections, some new beams with complex cross sections were constructed by combing these simple beams or adding reinforce ribs to these simple beams.
For waveguides with simple cross sections, such as plates and circular rods, it is shown that the Euler Bernoulli beam model provides acceptable results over the majority of the fd range where there is measurable sensitivity to load.
Back at his office, on Fifth Avenue, Taubman took a piece of paper and drew a simple cross-section of a two-story building.
The accuracy and applicability of the model to wind engineering problems are successfully assessed by computing the aerodynamic behaviour of some simple cross-section shapes.
A miniature extrusion line using a micro-extruder was developed and used to produce extrudates with a simple cross-section from a few grams of raw polymer material.
Extra parameters are required for model optimization but simple cross-section surveys (area and velocity) provide enough information to ensure enhanced parameter reliability.
It is worth noting that only a very simple cross-section image analysis of the unidirectional composite medium is required to provide the two morphological parameters needed to predict the overall diffusivity tensor.
We also use FEA to show that when trying to approximate a realistic trapezoidal 3D tipped geometry, there exists a systematic overestimation in cantilever stiffness of ±2%, compared to when considering a simple rectangular cross section.
Products may have either a simple or a complex cross section; examples of complex extrusions can be found in aluminum window frames.
