Modulus of
elasticity and Poisson's ratio are two material properties whose values are
often used as input parameters in design, stress analysis and simulation of
structures or machine element components. So far, the determination of both
material properties uses modern methods which require quite expensive measuring
instruments and measuring tools that have a high level of accuracy. In this
study, the use of the on-off method in tensile testing to determine the elastic
modulus of four types of metals is investigated. The four types of metal are
AISI 1018 steel, AISI 1045 steel, stainless steel 304 and aluminum 1100. The
results obtained show that the elastic modulus obtained is close to the
reference elastic modulus value. Meanwhile, the Poisson's ratio resulting from
this method is still not close to the Poisson's ratio from the reference. For
this reason, measuring instruments that have higher accuracy are needed to get
good results.
