Carbon Fiber Strip Buckling Force Problem

Click For Summary
SUMMARY

The discussion focuses on utilizing Carbon Fiber Reinforced Polymer (CFRP) sheets as spring actuators by exploiting their buckling behavior. Key inquiries include determining the force exerted during buckling under various parameters, the necessary displacement for buckling, and the force required to initiate buckling. The CFRP strip is supported at both ends by pin joints and is initially bent, with a lateral force applied to induce buckling. Participants suggest using simulation software for analysis, emphasizing the importance of accurate modeling in predicting performance.

PREREQUISITES
  • Understanding of CFRP material properties and behavior
  • Knowledge of buckling theory in structural mechanics
  • Familiarity with simulation software for structural analysis
  • Basic principles of mechanical forces and displacement
NEXT STEPS
  • Research "ANSYS Mechanical" for simulating CFRP buckling behavior
  • Explore "MATLAB" for analytical modeling of buckling forces
  • Study "Euler's Buckling Theory" to understand critical load calculations
  • Investigate "Finite Element Analysis (FEA)" techniques for accurate predictions
USEFUL FOR

Mechanical engineers, materials scientists, and researchers interested in the application of CFRP materials in structural design and buckling analysis.

Hey,

So I`ve been trying to wrap my mind on how to solve this problem. I`m trying to use a CFRP Sheet as sort of a spring actuator by using it`s buckling phenomena to deliver a force to the body it`s attached to. Kind of vague so here is a video:

This video does it electrically, but I want to be able to do this by using mechanical forces.

What i want to know are:
1) The force it will exert when it does buckle under different parameters (that whipping motion)
2) What displacement it needs for it to buckle
3) How much force needed to push it to its buckling point.

This strip will be supported at both ends by a pin joint and will initially be bent to one side. The only external force that will be acting is a force acting laterally on the strip to displace it so it can reach the point where it will buckle to the other side.

I`m not actually sure where to start with this. I can either use simulation software to solve for these (If you can point me to the right software for this that`d be great!). Or I can do it the hard way and use pen and paper. Can someone point me to the right direction?
