Dynamic Stress analysis of a structure

Recommended Posts

I want to perform Dynamic Stress analysis on a structure undergoing high magnitude and high frequency loads please suggest me some tutorial and viedos 

thank you

Hi,

Please specify the type of dynamic analysis you are performing (like crash, bird strike, fan blade out...ets).

Please go through RADIOSS training series in YouTube, where all the concepts are explained. You can access the webinar at: https://www.youtube.com/watch?v=HGsA5RwddLs&list=PL1u26y75SCrA_BOCLaSewVCNY7xRvCTnA

Also, please watch another training video which covers Crash Analysis using RADIOSS with HyperCrash preprocessor at http://www.altairuniversity.com/learning-library/2017-winter-directed-learning-webinar-series-crash-analysis-with-radioss/

 

Attaching the model files and document for bird strike analysis, which is a high speed impact analysis.

Hi,

RADIOSS bulk is used for implicit analysis whereas RADIOSS Block is used for explicit analysis.

In the latest versions there is no RADIOSS bulk and all implicit is under OptiStruct. 

Different block formats (110,120,130,140,2017) shows the respective HyperWorks version.

Any video for explicit transient stress analysis of structure under high magnitude load applied on it?Loading timing is in the milliseconds.

Hi,

It is possible to perform nonlinear transient analysis in RADIOSS. You can impose displacement on to the component with the curve.

Please go through RD-3595: Three Point Bending with HyperMesh and Example 42 - Rubber Ring: Crush and Slide from the Help Menu which are similar case

Hi,

You can use  Concentrated Loads (/CLOAD) load collector where you can define Force v/s Time function.

The beam is fixed and force vs time plot is given how to do its transient analysis with other end fix and load applied as shown in figure
