How to Calculate Shear Force on a Bolted Connection | FEA for beginners | SolidWorks Simulation

hello everyone on on this video we are going to learn how to uh simulate this bolte connection and and find the the shear force acting on each Bolt there is going to be a force acting on that direction and that Force value is going to be 5000 pounds Force so let's go to SolidWorks and um this is the assembly that I created to simulate the two plates and the bolts will be um placed on these holes already made so from here we can go to the simulation if you don't have the simulation tab you can just right click and select simulation and it'll appear here next we can um create a new study and we can rename this as voltage connection and you can say this is a Shear type and let's hit okay the first thing we have to do is apply a material to the to the plate for this problem let's select the 1045 still and let's hit close next we'll apply a fixed geometry to the um it's applied to the bottom of this plate and we'll keep the fixed geometry type and let's hit okay next let's apply a force as I mentioned to you there will be a Shear force acting on the bolts so we we put the force here and the magnitude is going to be 5000 pound Force and let's revert reverse Direction let's hit okay under connect connections let's right click and select the um the bolt connector so there are a few um connector types for this problem we're going to use the um the standard bolt with a nut so there will be two boxes here the first one is going to be for the bolt and the next box is going to be for the nuts so let's select the um the bolt so we need to select the edge what the bolt is going to be uh look at it if you notice um the um the diameter of the bolts is automatically calculated for you right here and the um the head diameter there is a factor of 1.5 times the the shank diameter this is a default value but if you if you happen to know the head diameter you can change this so now let's select the nut the nuts will be on the other side of the connection so select the face so after you select those two we can scroll down and we're going to keep the distributed connection type this connection type allows the faces attached to the ball connectors to the form which delivers a more realistic simulation of a connectors Behavior under material if you have a custom material you can Define your own material properties uh for now we can just we're just going to keep alloy still strength data select this option if the first option is if you know the um stress area otherwise let's select the calculator stress area and let the program calculate that for you so the thirds per inch this is a value that comes with the Bold specs so for this type we're going to select 10 and the ball strength we're going to make it um let's make this 75 000. PSI safety Factor this is the um this is the desired safety factor that we would like to achieve so for now we'll leave it at two but you can always change it and we are not changing the anything on the advanced options or simple settings looks like we have all the parameters completed so we have to follow the same step for the other Bolt and uh for that we are just going to keep these keep visible pin and let's hit okay so by doing that all the settings that we created are going to stay the same all we have to do is select the edge for the other bolts so so that will be the bolt and now select the nut on the other side and let's hit okay and close it now let's apply some um local interactions so let's go to connections right click and select local interaction and we want SolidWorks to locate that for us so we're going to select the two plates that we created and click on find local interactions after we do that we can hit OK you'll get the message saying that they found a local interaction so let's click yes um it looks like we have all the settings that we need so we have the material we have the connection we have the bolts we have the fixture external load now we need to mesh great mesh right click and create mesh and let's hit OK and now we're ready to start the simulation let's run this study the simulation has been completed now we are ready to obtain the the shear Force acting on on those bolts for that we can right click on the results and we're going to select Define pin bolt check plot and let's hit okay after we do that we can select details from this window and before we check the values so since we apply a a force equal to 5000 pound force on this direction so I'm expecting the shear Force um on each ball to be 2500 because that force will be divided by these two uh by these two volts so once we um we click on details we we will get this window from here we can here make sure that you have a bolts and on the units select IPS and from here uh these first three rows are um are related to not number one and the other three are related to the bolt number two so looking at the shear Force for boat number one we see a force on the Z Direction and The resultant equal to 2500 pound force and for the Bold number two also 2500 volt uh pound force and that's what we um we expected um for these two bolts we can we can close this window and there is another way to chat to check that is uh you can just right click on the results and um now we're going to select list connector force after you do that uh make sure that you have the connected Force checked and changed the units and we can see it from here that the same value is obtained the shear Force 2500 this is for bolt number one and for Board number two it's also 2500. um if you want to see the displacement and you want to animate how this is going to behave when acting on when the force is acting on those two plates we can right click on displacement and click on animate and you have a a visual representation of of this uh both the connection similarly we can go to the stress and um we can also animate under the stress and uh and this concludes this tutorial I hope you enjoy and uh thank you for watching
