Correct Answer : The stress value produced when Pe,n is utilized in the equation of modulus of rupture to represent the average flexural strength in the post-peak zone up to a specific deflection of L/n
Explanation : Equivalent flexural strength is the stress value that represents the average flexural strength in the post-peak zone up to a certain deflection of L/n obtained when Pe,n is employed in the equation of modulus of rupture.
