McHenry Forum - Crash Reconstruction & Simulation

Today i received an invoice from AT&T (yes some of us still request paper invoices!) On the back of the envelope i noticed a note: att envelope.jpg Here's the website https://www.itcanwait.com/ Here's the video link: https://www.youtube.com/watch?v=o1wBO3x8NEE Good message, It Can Wait, and inte...

For some levity see recent article... What’s the Sweetest, Crispiest Way to Stay Safe in a Car Crash? Would a large Rice Krispie square meet current guidelines for temporary highway traffic barriers? barrier materials.jpg See the article for more information and some levity! What’s the Sweetest, Cri...

After responding to a recent question on determining DeltaV from acceleration I realized this thread should also include some fundamentals on integration to determine velocity and displacement. I did a quick search of the internet and here is an example of some related notes: Finding Velocity and Di...

New: Use this link to go to the latest post on this thread Q: (Posted to Crash Forum and with no answers after 3 days i decided to respond and also post here) Hi, is it possible to calculate the lateral Delta-V from the acceleration rates? I have a long delta v. Target vehicle hit on the near side ...

Saw this on Linkedin 100+ Car Accident Statistics for 2019 Which begins: In the United States and throughout much of the world, automobiles are a way of life – and car accidents are an inevitability. With more than 143 million Americans commuting daily, there’s no doubt that car accidents are bound ...

Q:Thanks for the info. I guess I should have provided more information on the crash. The vehicle in question completed a straight skid and struck the area of the rear axle of a box truck that was in the process of a left turn. The rotation was initiated because of this impact not due to oversteerin...

A couple of clues which will help the SMAC user to determine if a CCI is required. First you may get this error message: CCI related error message.jpg This indicates that there was a force balance issue in a SMAC simulation. another indication is if you run a simulation in 2D and then 3D and get dra...

Here's a quick first pass simulation at 80 MPH of the launch and travel to landing impact into a building per recent updates. Tried some locations, and different focal lengths for the roadside camera but couldn't match. Will revisit later. NOTE: This is a DRAFT : We only spend an hour or so preparin...
