Question: derive the equation for the distribution of the normal fiber...

Question details

Derive equation for the distribution of the normal fiber stress (eq. 8 in the paper) in the debonded region (ml). Refer to the below schematics. Show the details of your work. Hint: use equilibrium condition for a fiber segment 4. ml

Partially elastic model This model, due to Piggott, assumes that debonding occurs over a distance ml/2 from the fibre ends, with 0<m<1. Perfect adhesiorn holds in the central part of the fibre. In view of eqn (3), the stress distribution in the debonding zone reads o,-4t(1-x)/d (8) 40 2 20 -20 40 100 200 -100 100 200 300 Dimensionless Axial Distance (x/r)
