| Abstract Scope |
The use of additive manufacturing (AM) for continuous fiber-reinforced metal matrix composites (CF-MMCs) opens doors for innovative light and high-temperature applications in the fields of aerospace and energy. But while AM also lends itself to a whole host of new complications, such as the problem of unusual porosity and incomplete fiber matrix wetting, as well as residual stresses that result from the process. All of these process-related complications function as starting points for creep deformation and progressive failure at elevated temperatures.
This paper describes a new computational platform based on Anissing Continuum Damage Mechanics (CDM) used to simulate the correlation between Creep and damage. The thermodynamics-based model makes it possible to define the laws of damage evolution related to the alteration of stiffness depending on the fiber direction and the direction of the matrix. The model has been validated against experimental data. |
