Get PriceImpact forces (caused, e.g., by a fall) can be much greater than static forces, because the speed of sound in solids is so high (and therefore t s o u n d so small). This is a fact of experience (balancing a brick on your head is fairly easy and painless, in contrast to having it fall on your head from a height of several meters), but now we

Get Price[]### Estimating and measuring impact forces by projectiles

The impact action of a projectile can cause the target element to deflect as if the action was a static force and can also inflict damage to the target in the vicinity of the point of contact. In extreme conditions, perforation or indentation into the target can occur because of the very high contact force generated by the impact.

Get PriceHow You Can Protect Against Impact Force. So, let me answer your question—just what is impact force and how to protect against it? Impact force transfers the energy of the shock of a collision to your products, equipment, and workers. Clearly this is unwanted energy that causes damage and injury and, ultimately, rework, waste, and downtime.
