You can also define custom material models. Many other material models and physical properties can be defined in Workbench, including Plasticity, Hyperelastic, Viscoelastic, Creep and Fracture Criteria options. YoungвЂ™s Modulus is 3.1E9 N/m^2 (Pa), PoissonвЂ™s ratio is 0.3, and I have used a typical polyimide value of 1,430 kg/m^3 for density (this is not defined in the benchmark). I have selected project units to be Kg, m, S. The yellow highlighted regions show where to input the data. I have created a material called вЂњbenchmarkвЂќ by clicking on the Isotropic Elasticity and Density options. The shallow roof benchmark material is assumed to be a type of polyimide, based on the defined material properties. To change this, double-click on the Engineering Data cell and the Material Input forms appear as shown in Fig. 3 shows I have a checkmark against the Engineering Data cell, but this is based on automatic loading of a default material. I will be using both Static Structural (which includes non-linear analysis) and Transient Structural.Д®ach step of the workflow is completed in turn, and a checkmark appears when the data is acceptable to ANSYS Workbench. The corresponding workflow is shown in the Project Schematic graphics window. I have selected the Static Structural Analysis System. 3:В Workbench Interface showing Static Structural workflow selected and highlighted (inset). In addition to the mechanical-based solutions, this can embrace computational fluid dynamics (CFD), thermal, electromagnetic and others.ДЇig. In the main Toolbox menu, we can see a wide range of Analysis Systems available, based on the physics applications purchased. On launching ANSYS Workbench, the main user interface appears as shown in Fig. I used ANSYS to explore the physics of this benchmark more deeply, in particular, looking at contact and dynamic loading. The plate will tend to move away from whatever is loading the central point during snap-through and the snap-through will be dynamic in nature. The discussion was based on the fact that none of these loadings is realistic. arc length displacement-controlled loading that permits reverse displacement (вЂњsnap-backвЂќ). displacement-controlled loading that is enforced at the center point andДЈ. force-controlled loading that applies a monotonically increasing force at the center point Дў. The three classic types of loading are:ДЎ. This implies counterbalancing forces and reversal of motion at the center point during the snap-through. This is impractical once snap-through has started. The reason it is flawed is that static stability is required at each load step in the benchmark. It has been used as a benchmark for many years.ДЄs I mentioned in a previous DE article ( January 2018, вЂњDemos and BenchmarksвЂќ), it is a typical example of a benchmark that is numerically challenging but is flawed, practically speaking. There are many real-world examples of snap-through, such as the lid of an oil drum with an internal vapor pressure, mechanical switch systems or metal вЂњclickersвЂќ for dog training. The debate is in how the transition occurs. The red line shows the overall вЂњjumpвЂќ from one configuration to another.
