How to Calculate Critical fiber length?
Critical fiber length calculator uses Critical fiber length=Tensile strength*Fiber diameter/(2*Critical shear stress) to calculate the Critical fiber length, Critical fiber length is necessary for effective strengthening and stiffening
of the composite material. Critical fiber length and is denoted by l_{c} symbol.
How to calculate Critical fiber length using this online calculator? To use this online calculator for Critical fiber length, enter Tensile strength (TS), Fiber diameter (d) and Critical shear stress (τ_{c}) and hit the calculate button. Here is how the Critical fiber length calculation can be explained with given input values -> 0.00625 = 100000000*1E-05/(2*80000000).
