In ASME B31.3 it is stated that,

"A displacement stress range greater than that permitted
by para. 302.3.5(d) may be allowable if due consideration
is given to avoidance of excessive localized strain and
end reactions."

My question is that what is the limit for the excessive localised strain & end reaction with reference to above statement & upto what extend the allowable stresses can be incresed by limiting the end recations & localised excessive strain.
