ABOUT
PROJECT TIMELINE

Project description: In this project, the static and buckling analysis of a multilayer carbon fiber/epoxy laminated composite fork have been done with its degradation in external environmental conditions. The static stress to strength ratio in three composite failure theories and critical buckling load has been obtained from the finite element analysis in Abaqus. 

Objectives:
1) To design a multilayer laminated bicycle front fork.
2) To optimize the design for minimized weight and uses three failure criterion to predict damage. 
3) To find design variable (Zeta) to avoid buckling failure with a safety factor.
