TL;DR Summary
A car hits a mass of soil with the impact force of F. We know properties of the mass and its dimension. What is the force felt at the other side of the mass?
Hello,

Please see the attached sketch. A car hits a mass of soil and applies the impact force of F. The force/wave travels the distance L through the mass at the end of which there is a wall so I think the force attenuates. Assume we have all the properties of the mass. My question is, what would be the attenuated/decreased F felt by the wall? I know this can be modeled with FEM but I have a feeling there should be an analytical solution based on physics for it too. Would really appreciate any insight.

Can you say what the context of the question is?

Not sure what you mean by the context. Let's say you want to design the wall to withstand the force but you know the force felt by the wall will be reduced due to existence of the mass of soil.

Why are you anticipating a car running into your wall so that you need to add protection?

This looks like some sort of accident investigation. Please be aware that we can't provide any legal advice in situations like this.

1. What is impact force reduction after passing through a medium?

Impact force reduction after passing through a medium refers to the decrease in the force of impact experienced by an object after it has passed through a substance or material. This can be caused by factors such as absorption, dispersion, or redirection of the force.

2. How does passing through a medium affect impact force?

When an object passes through a medium, the medium can absorb some of the energy from the impact, reducing the force applied to the object. Additionally, the medium can also disperse or redirect the force, further reducing its impact on the object.

3. What types of materials can reduce impact force?

Various materials can reduce impact force, including soft materials like foam or rubber, as well as hard materials like metal or plastic. The effectiveness of the material in reducing impact force depends on its properties, such as density, elasticity, and thickness.

4. How is impact force reduction measured?

Impact force reduction can be measured using various methods, such as force sensors, accelerometers, and high-speed cameras. These tools can capture and analyze the force applied to an object before and after passing through a medium, providing data on the reduction in impact force.

5. Why is understanding impact force reduction important?

Understanding impact force reduction is crucial in various fields, including engineering, sports, and safety. It allows for the design of materials and structures that can better protect against impacts, as well as the development of safety protocols and equipment to reduce the risk of injury in high-impact situations.
