10 Beams

The Beams chapter contains most, if not all, of the formulas in chapter Beams of the textbook. CADEC can deal with open and single-cell closed sections of arbitrary shape, symmetric or not. CADEC will calculate everything that can be calculated with the classical theory of thin walled beams, including axial, bending, torsional, and shear stiffness; the position of the neutral axis and the shear center, etc. [8].

The shape of the section can be drawn in My Sections as a set of straight lines that represent the cross section of the beam. Also there, you choose the laminates that make up each of the panels. Notice that you have absolute freedom to mix and match whatever laminates you want.

In My Section Loads, you define the loads to apply to the beam. Then, you come to Chapters to do the analysis. To illustrate the analysis of thin wall beams, we use Example 10.5 of the textbook. All the data is included in your database from the moment you register for an account in cadec-online.com. The geometry and material definitions were done in My Documents/Edit page, which is reproduced below:
