Continuum Damage Mechanics (CDM) is a powerful tool to |
|
solve problems such as large plastic deformation, Where |
|
the fracture mechanics is unable to analysis of its |
|
effects. Continuum damage mechanics in terms of the |
|
internal variable theory of thermodynamics is derived and |
|
based on the experimental results on material properties |
|
is developed. As regards, Aluminum has an important role |
|
in designing and construction of aerospace structures and |
|
devices, since its density and strength are suitable to |
|
aerospace applications. Al 5083 is one of the most widely |
|
used materials in the construction of missiles, space |
|
vehicles and sounding rocket structure. In this paper, |
|
the continuum damage mechanics principles are studied. |
|
Nucleation, development and propagation of damage in Al |
|
5083 are investigated based on Bonora model as a non- |
|
linear model. FE simulation of material behavior during |
|
failures is carried out by ABAQUS software package and |
|
USDFLD subroutine. The results are validated with |
|
experimental tests. This comparison shows that the |
|
simulation results are agree with that of experimental |
|
tests, also the Bonora model can be used of damage |
|
modeling of AL 5083. |
