ANALISIS MODULUS ELASTISITAS DAN ANGKA POISSON BAHAN DENGAN UJI TARIK
ABSTRACT: Observation of
the stress and strain in materials
steel, brass and anneal is done
by testing to determine the
tensile modulus of elasticity of the material. The results showed that the
modulus of elasticity of the material brass is smaller than the brass alloy
steel and steel materials, caused by the formation of the composition of the
material is different. The relationship between stress and strain
are used to
gain slope value,
and this value
used to determine
the modulus ofelasticity of steel
materials, brass and
anneal. The analysis showed that the magnitude of the modulus
of elasticity of
brass material brass=(20.10 1.60)
x109Pa, anneal materialsanneal=(68.10
2.20) x109Pa, and steel materials steel=(201, 00 5.30) x109Pa.
The results oftensile tests conducted
on all three materials can
be used
to determine the comparative
figures Poisson. The analysis
showed the amount
of comparative figures
in steel material
Poisson msteel =0.106 0.002, brass
material mbrass =0.104 0.002 and
anneal materials manneal =0.103 0.005.
Figures Poisson appeal on steel materials is greater than the brass and anneal.
