Dear All,

I am writing to introduce to you a general-purpose composite beam solver, GEBT, which can capture all the geometrical nonlinearity obtainable by the six fundamental deformation modes (extension, torsion, bending in two directions, and shearing in two directions), and the coupling between these fundamental deformantion modes, such as extension-twist coupling commonly existing in initially twisted rotorblades. The features of GEBT are:

I'm writing this post cause it took me much time to find some free softwares that can record activities from screen for Windows and Mac systems. I use both OS at office and lab.

I'm doing some experiments. One is to measure the deformation of microcapsules, both loading curves and deforming capsules via a light microscope displaying on the screen; another is to observe the movement of nano/microcapsules in a cell. For both cases everything is displayed on the screen. I want to record them for kind of live show without using any external recorder and then converting clips.
