Three-dimensional modelling of tensile behaviour for standard aluminium specimens

Abstract: The effect of specimen width and incorporation of a
circular hole on the tensile behaviour of commercially available
aluminium alloy AA 1100 was studied using finite element analysis (FEA)
for convergence with the already published experimental work of other
researchers. Static structural analysis was conducted to simulate
tensile loading of Japanese industrial standard (JIS) specimen JIS Z
2201 No. 13B and No. 5 until the point of the ultimate tensile strength
(UTS) was reached. A strain rate of 0.25 mm/s was used for both the neat
specimen and the one bearing a circular hole of 8 mm in diameter at the
centre of the specimen. The numerical results exhibited a good agreement
with the experimental work by comparison of the percentage elongation
for numerical and experimental data. The normal stresses calculated
using analytical and numerical approaches also reflected a good
convergence. For neat specimens of JIS Z 2201 No. 13B and No. 5, a 100 %
increase in specimen width enhanced the load required to reach UTS by
100 %, while elongation was increased by 30 %. On the other hand, for
specimens of JIS Z 2201 No. 13B and No. 5, bearing an 8 mm circular hole
reduced the load required to reach UTS by 300 %, while elongation was
only increased by 25 %. The 200 % decrease in load required to reach UTS
and 57 % reduction in elongation was observed by incorporating an 8 mm
circular hole in the neat specimens.
Keywords:
aluminium alloy, material testing, finite element analysis, stress
magnification.
