Abstract

Elastic modulus of small specimens and thin films can be determined in bending tests using cantilever or three-point arrangement. The paper presents the basic formulae for these measurements, analyzes the errors which can arise, and shows how they can be reduced. The use of the method is illustrated on glass, silicon, and glass coated with TbDyFe.
