Roof crush laboratory tests (simulating rollover car behavior) usually take 10 to 30 seconds to crush the car to the required maximum displacement of the crushing panel. Therefore, it is clearly an almost static or quasi-static problem. It is apparent...
In a previous Brief, we presented some structural analysis results of the superconducting coil of the Wendelstein 7-X, the world’s largest plasma fusion experimental device of the stellarator family.

Each time a neutrophil (cell) pass through the human lungs, it typically crosses over 50 capillary segments. The transit time of the neutrophil depends on its deformability, surface tension, pressure drop across the capillary, and the geometry of the capillary.

In civil engineering design and analysis, the effects of fluids on the motion of structures can be very important. This is particularly true in seismic analysis of liquid storage tanks. In this class of problems, the fluid and tank motions...
The ADINA-TMC (Thermo-Mechanical Coupling) program is a powerful tool for fully coupled thermo-mechanical analysis of problems in which the thermal solution affects the structural solution and the structural solution in turn affects the thermal solution. ADINA-TMC takes into account such effects...
The above animation depicts an axisymmetric model of a mono-tube gas shock absorber, with its schematic beside it. The piston inside the casing pushes its way through the oil (the hydraulic fluid which in reality is a mixture of oil...
FSI (fluid-structure interaction) analysis has many applications in the automotive industry such as the analysis of shock absorbers and valve mechanisms. In the ADINA System, the ADINA-FSI program provides fully coupled analysis of fluid flow with structural interaction problems, meeting...
Nonlinear cyclic symmetry analysis is a new feature in ADINA 8.1 that can be used for static, dynamic and frequency analyses. In static and dynamic analyses, the loads applied to each cyclic part must be identical (when rotated around the...
The new surface tension option is implemented in the ADINA program, version 8.0. This new option allows the user to assign a surface tension value to selected lines (for 2-D planar and axisymmetric problems) or surfaces (for 3-D problems). The...
