Question
What is the interaction formula?
Expert Solution

Step 1
When the structures are under combined loading then to determine the failure in them interaction formula is used. Compress loading includes both shear and normal stress. These are written in the form of ratios, and expression for interaction equation is given as:
Where, Rσm is normal stress ratio, R?n is the shear stress ratio, m and n are arbitrary constants and defined experimentally.
