What is equivalent flexural strength?

• A. The stress value obtained when the peak load value is used in the equation of modulus of rupture
• B. The stress value representing the average flexural strength in the post peak region up to a specified deflection of L/n obtained when Pe,n is used in the equation of modulus of rupture
• C. The load value representing the average load-carrying capacity in the post peak region up to a specified deflection of L/n
• D. Value of the mean equivalent flexural strength normalized with respect to mean flexural strength
