| dc.description.abstract | In this project, the correlation between experimental data and simulation analysis to elucidate
deformation behaviors and thermal stamping processes of engineered materials. The tensile,
compressive, and flexural properties of aluminum alloy Al5052-H32 were assessed at strain rates
from 0.001 to 2500 s⁻¹, aspect ratios of 0.5 and 1.5, and temperatures between 25°C and 450°C.
Quasi-static and dynamic testing demonstrated the alloy's vulnerability to Portevin–Le Chatelier
effects, with stress-strain curves indicating peak stresses reaching 291 MPa where minimum
ultimate stress is 216 MPa in tensile tests. Fracture processes shifted from ductile to brittle at rising
temperatures, as shown by simulation result of the fracture surface morphology. On the other hand,
in compression test the lowest ultimate compression stress is 199 MPa and the maximum ultimate
stress is 368 MPa, that increase rate is almost doubled. Furthermore, for flexural test where
minimal ultimate stress is 399 MPa but peak ultimate stress is 401 MPa. Where deviation overall
is less than 3% for this three test, it means simulation result is quite align with the experimental
data. Experimental and finite element simulations were conducted to investigate thermal stamping
methods for alloy sheets, which are crucial in aerospace and marine applications. | en_US |
