In this technical note, analytical solutions for the elastic buckling of heavy columns with various combinations of end conditions are derived, for the first time, in terms of generalized hypergeometric functions. The benchmark solutions may be used to assess the accuracy of approximate formulas and numerical solutions. DOI: 10.1061/ ASCE 0733-9399 2008 134:1 116 CE Database subject headings: C...

We describe a system for interactive animation of cloth, which can be used in e-commerce applications, games or even in virtual prototyping systems. In order not to restrict the shape of the cloth we use a triangulated mesh, which serves as basis of a mass-spring system. For the animation of the particles internal and external forces are considered. Since cloth is a very rigid material when str...
