Spring Constant and damping factors for foam rubbers

WebFoam materials are generally not used for applications where tension and shear loading are dominant. However, they are usually used where compression loads are expected. The most attractive feature of foams is the ability to undergo a large strain deformation while maintaining a low constant stress level before the densification region [22]. WebA foam dart launcher is loaded by compressing a spring with spring constant k by Δx. When the trigger is pulled the spring is released pushing the foam dart out of the launcher. The foam dart launcher is held off the edge of a roof, h off the ground and is pointed straight down when launched. The foam dart hits the ground with a speed of v.

"WebThe force F the spring exerts on the object is in a direction opposite to the displacement of the free end. If the x-axis of a coordinate system is chosen parallel to the spring and the equilibrium position of the free end of the spring is at x = 0, then F = -kx. The proportional constant k is called the spring constant. It is a measure of the ... " - Foam spring constant
