How Can I Find Mid point Deflection of this Beam
i want the mid point deflection in case of "four point bend test" on a
specimen of length 140mm, width of 40mm and thickness of 10mm.
Problem is that, beam theory is valid if the cross-sectional
dimensions are less than axial dimensions. Here this condition is
violated. i had modeled the specimen in Abaqus and the diffection at
mid point is almost double that of the actual diffection calculated
from beam theory.
how can i find the theoritical difflection at mid point in this case?
i had one option, using timoshenko beam theory and applying larger
deflection theory. will it be a reasonable approximation in this case?
