# Impact analysis in ansys workbench

## Impact analysis in ansys workbench

(OP)
Good evening to everyone, I want to do impact analysis in ansys workbench, I got input as energy (5KJ) that will be impact in my object. I can’t able to apply as energy, any Idea like how to feed the inputs. I don’t have mass information I have only energy value, please let me know anybody know how to apply?
Thanks

### RE: Impact analysis in ansys workbench

Describe problem more specific. Do you hit structure with bullet or drop structure onto ground?

Hi thanks for your reply. Solid object hitting the structure. So for I didn’t get actual mass of the object, customer gave only joule. He’s there any way i can to impact with joule value

Hi everyove
I know the energy value = 5 kJ. Using potential energy equation (PE=mgh). I know the object is hitting 500 mm radius (5000=m*9.81*.5) that gives mass value = 1019 kg. Can we use this mass value in kinematic equation to find velocity (KE= 0.5mv2).I assume (KE=PE),therefore my velocity v=3.13 m/sec.
please let me know whether this approach is ok or not.
Thanks

How do you use potential energy equation - what is h in your case? You have to make assumption about mass and then calculate velocity from kinetic energy. There are big difference between coin with 5kJ kinetic energy and pilow with same energy (also coin and pilow with same KE will hav different momentum).

(OP)
h 500 mm.

what will be the solution ?

### RE: Impact analysis in ansys workbench

What is h? Can you show it on picture? I dont understand.

### RE: Impact analysis in ansys workbench

Now I understand. Yes your calculations look right.
But now you are facing new problem - impactor maus have some radius.

### RE: Impact analysis in ansys workbench

Radius value included in the calculation. What will be solution?

Products come in all shapes and sizes, and customers demand solutions tailored to their needs. With mass customization software, these two facts can be reconciled in an automated, customer-facing experience called a product configurator. In this engineering.com research report, we examine the different levels of mass customization with the pyramid of product configurators. Taking a look at real-world case studies, we discover how the highest level of the pyramid can enable true engineering automation, saving time and increasing customer satisfaction. Download Now
Research Report - Test and Simulation Survey
We at engineering.com continually hear how engineers and designers will be doing simulation, such as FEA and CFD, and that they will be doing it early in the design cycle. Is this wishful thinking? We found out what it is really like in industry. Read more now. Download Now
White Paper - Effects of AIA Quick Guide to UL 489 or UL 1077
The function of a circuit breaker is to provide overload (thermal) and short-circuit (magnetic) protection to a circuit and its downstream components. A circuit breaker functions like an airbag in a car, protecting circuit components and people by tripping the circuit to interrupt the current flow if it detects a fault condition in the control system.

White Paper - Guide to Integrate Large-Format Additive
As with any new technology, getting into large-format 3D printing begins with investigation. The first question may be a simple one: what does “large-format” mean? For 3D printers, “large” is a relative term. Many extrusion-based (FFF) 3D printers are referred to as desktop machines, because they fit on table space. Some of these have very respectable build volumes – but when it comes to “large-format,” the machines will need their own dedicated floor space. Large-format 3D printers have significant build volumes and are most often found in professional settings, like manufacturing facilities and R&D centers. Download Now
