Abstract: This paper outlines an approach to teaching Statics that is organized around five topics: free body diagrams, equilibrium, equivalence, separation of rigid bodies, and friction, without ...

This paper proposes a gradient projection method to solve the equilibrium problems where the bifunction is quasiconvex in its second argument. We use the Greenberg-Pierskalla quasi-subdifferential of ...

THIS is a compilation of sixty problems in graphical statics, many of them taken, by permission, from the army entrance examination papers. Each problem is accompanied by a diagram, and has a separate ...

MPSpack is a user-friendly and fully object-oriented MATLAB toolbox that implements the method of particular solutions (aka Trefftz or nonpolynomial FEM, including the method of fundamental solutions, ...

Numerical simulation results of basic exactly solvable fluid flows using the previously proposed by H. Chen Lattice Boltzmann Method (LBM) formulated on a general curvilinear coordinate system are ...

A new study demonstrates a new, counterintuitive way to protect atomically-thin electronics -- adding vibrations, to reduce vibrations. By squeezing a liquid-metal gallium droplet, graphene devices ...

Two-dimensional (2D) irregular packing problems are widespread in manufacturing industries such as shipbuilding, metalworking, automotive production, aerospace, clothing and furniture manufacturing.
