This example shows further results of a helmet impact analysis (courtesy of MET S.p.A., Italy). This time the head and helmet both have an initial speed of 5 m/s and side-impact a rigid anvil. This is one of several impact...

ADINA is known for its powerful capabilities in the solution of fluid structure interaction (FSI) problems. For many years, ADINA FSI solutions have been used successfully for many applications in a wide range of industries. Although ADINA FSI is a...
Blow molding is a process frequently used to manufacture hollow plastic objects such as bottles and tanks. A molten plastic tube (parison) is extruded into the mold and pinched at one end. Compressed air is then blown into the parison...
Bolts are an integral part of engineering designs, and bolted structures can show a complex mechanical behavior. Not long ago, bolted structural parts were commonly treated as rigidly connected. With recent advances in computer-aided modeling and finite element analysis, engineers...
In fluid flow analysis, we ideally can use relatively coarse meshes and still get reasonable solutions in the flow and pressure predictions, even for high Reynolds and Peclet number flows. We would also like to have a true consistent tangent...

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...
