| dc.description.abstract1 | The Elastic Modulus Measurement through Ambient Response Method (EMM-ARM) is
designed to continuously monitor the elastic modulus of hardening construction materials such as
concrete, cement paste, mortars, stabilized soils, and epoxy resin. In practice, a composite beam,
made of the tested material in its mould, is induced to vibration by means of environmental or
controlled excitation, and its resonant frequency is identified. The material’s elastic modulus can then
be calculated based on the vibration equation of structural systems. The traditional system to conduct
EMM-ARM experiments is based on specialized equipment and on proprietary licensed software,
which results in a considerable cost, as well as limited options for customization. The paper hereby
presented proposes a delve into the development and validation of a cost-effective and open-source
system that is able to conduct EMM-ARM experiments. By using a Raspberry Pi for the computing
device and cost-effective electronic components, the cost of the system was one-twentieth of the
traditional one, without compromising the measurement reliability. The composite beam’s excitation
is generated, while the vibration response is recorded by the proposed system simultaneously, since
the Raspberry Pi supports multiprocessing programming techniques. The flexibility earned by the
exclusive use of open-source and cost-effective resources creates countless application possibilities
for the proposed system. | pt_BR |
