Differences between stress-based and strain-based criteria are investigated in seismic performance evaluation of the arch dams in time domain. A numerical model of the coupled dam-reservoir-foundation system is prepared with the finite element technique. Reservoir is modeled using the Eulerian approach as a compressible domain, and the foundation rock is assumed to be massless. Dynamic equilibr...

In the present study, the finite element method is developed for the static analysis of nano-beams under the Winkler foundation and the uniform load. The small scale effect along with Eringen's nonlocal elasticity theory is taken into account. The governing equations are derived based on the minimum potential energy principle. Galerkin weighted residual method is used to obtain the finite eleme...

This study explored how levels of automation (LOA) influence human robot collaboration when operating at different workload. Two LOA modes were designed, implemented, and evaluated in an experimental collaborative assembly task setup for four workload composed a secondary complexity. A user conducted involving 80 participants was assessed through two constructs especially designed the evaluatio...
