II.1.10.25 Honeycomb shear criterion

Depending on the modelling, the component σ33 of the Cauchy stress tensor is sometimes zero. Then a simplified “shear” criterion is often used:

FIHoneyShear = ( τ23 τ23all ) 2 + ( τ31 τ31all ) 2.

Core passes the failure criterion if the following condition is satisfied

( τ23 τ23all ) 2 + ( τ31 τ31all ) 2 ≤ 1.

The reserve factor is calculated as follows:

RFHoneyShear = 1 FoS ⋅ FIHoneyShear,

and the strength ratio is given by:

SRHoneyShear = FoS ⋅ FIHoneyShear.

This criterion is referred to as “HoneyShear” in FeResPost.
