Euclidean Plane Geometry

What it does?: You give it a surface (explicit, parametric or implicit form) and a point on it and you'll get the equation of the tangent plane (in the same form as the surface is) at that point and besides you'll see the surface, the plane and the tangential point Xo.See for usage.Useful for...

calculates surface area A and its standard uncertainty uA for any arbitrary polygon in a plane given by coordinates x and y and their respective standard uncertainties ux and uy. The inputs are assumed to be VECTORS, x, ux, y and uy all should have the same size. The uncertainties are assumed to...

This file uses import_stl_fast to pull in model geometry and write an appropriate .facet file. If you require the ability to import binary stl files, import_stl_fast can be replaced with another importer from the file exchange.The current version does not have inputs for different materials.

The plane stress problem i.e a plate under uniform tension at its edges is solved. Plate is dicretized using isoparametric Q4 elements. Pre-processing is done using a standard FEM software. 2nd order Gaussian integration is used to get stiffness matrix. Results obtained are compared with standard...
