How to Set Up the Fluidity Parameter Ī³ of the Hoek-Brown Model with the Softening Model In the framework of numerical analyses of geomaterials, one of the classical problems for modeling the development of shear bands is the pathological mesh-dependence...
We present an analysis of turbulent flow in a straight pipe depicted in the animation and pressure drop diagram above. Although this problem can be solved more efficiently using 2-D axisymmetric elements, we used 3-D elements as a demonstration. The...
Has it ever occur to you that your structural engineering project is tight on time yet you are having doubt on your design? Even if you’ve got the best design tools at hand, you might find yourself asking questions like...
With a projected cost of GBP 6.8 billion, the Lower Thames Crossing (LTC) is Englandās single largest road investment project since the completion of the M25 more than 30 years ago. The project is unprecedented in size and scale, making...
Since the time of Leonardo Da Vinci, it has been recognized that the sinuses behind the aortic valve leaflets produce vortices that aid in closure with minimal trans-valvular pressure.

The animation shows particle tracing in a 2-D fluid-structure interaction problem. A periodic normal traction load is applied to the left boundary of the model. This load forces the fluid to flow over the flexible structure. Since the load is...
The need to study the coupled behavior between fluids and structures in the presence of heat effects arises in many applications, including heat exchangers, disc brake cooling, components mounted on printed circuit boards, and coolant pipes in power plants, among...
