Cellphone Drop Analysis Using ANSYS (Explicit Dynamic)

This video presents the cell phone drop test explicit dynamic analysis using ANSYS workbench. It highlights corner drop test, front face drop test and side edge drop test analysis. It explains the various to build the FEA deck of explicit dynamic drop test analysis such as material assignment, meshing, connections, initial velocity or drop height application, results extraction, etc.

I did same as what you did but it isn't touching the ground. I gave 0.001, 0.1 and even 1 nothing is changing please help me🙏.
It is just moving some distance and coming back..!

[@graspengineering9249]

Check the interaction and give frictionaless support between all the bodies.

[@philipp3665]

and an other question: why dont we have to define the contact between the ground plane and the smartphone? I generell I dont understand why you dont use the contact settings, maybe commonly used for nonlinear problems?

[@graspengineering9249]

For explicit dynamic their interactions between bodies instead of contacts. You can find in the connections.

[@philipp3665]

why dont we have to define grativy? I guess because the computing time for this problem is so less and we defined this in the velocity setting, right?

[@graspengineering9249]

It dynamic analysis no need to define gravity. You can easily verify this with reaction obtained with and without gravity.

Why not change the material of floor as concrete?

[@graspengineering9249]

Yes, you can consider concrete too.

I am not able to put a platform I made the phone how should I do I don't know can you please explain.

[@graspengineering9249]

Just create rectangular surface and define rigid properties to the platform.

[@rocking1sum]

Do you provide complete beginner to expert training on ansys

[@graspengineering9249]

We are planning to start training soon. Even you can find 100+ videos on our channel from cad modeling, meshing to analysis, reporting etc.

[@comedy_canvas]

Sir how did you make this geometry can you tell me

[@graspengineering9249]

We might have refer this geometry from grabcad library and simplified it.

How to define time in analysis settings??

[@graspengineering9249]

You can define tile in analysis setting. Please check our video in depth.

Im not getting solution..plz help...its showing error,plz check previos msg....whats the issue

[@graspengineering9249]

What is the error ?

[@igniteX00]

@@graspengineering9249 it is showing pre processing error sir

@@graspengineering9249 everything seems to be fine . When I click on solution... At last I get, pre processing error

[@Kubavat_krupa]

please tell me how can plate take in model

[@graspengineering9249]

Model the rectangular plate and define the rigid material properties or give higher stiffness value to the plate.

[@felipequinones5769]

My model took hours to do. Someone knows why?
(I already adjusted the sizing of the mesh)

[@graspengineering9249]

Check the minimum element length and try to increase the size of it. Explicit runs take time to solve, it might varries from few hours to few days.

[@chetansonigara7935]

plz provide cad model sir

will upload soon in our blog-post
