“…In addition, Hopperstad et al (2003), Børvik et al (2005), Bonora et al (2005) and Mirone (2007) performed tension tests with smooth and pre-notched specimens to validate their damage and fracture models for different stress triaxialities. Horstemeyer et al (2003) studied damage evolution in aluminum alloy notched specimens from a combination of experiments, finite element analyses as well as non-destructive and image analyses. The various methods all corroborated the same damage progression.…”

“…61 The damage evolution model has been used in several studies in combination with design of experiment (DOE) methodology to investigate the effect and relative importance of several microstructural parameters on damage evolution. [61][62][63][64][65][66][67] By using the method to study the influence of damage on a component subjected to load it was shown that the weight of the component could be significantly reduced without increasing the amount of damage obtained in the component. 68 Recent work shows the process of calibrating the ISV model for a specific alloy, 69 and the model is proposed as the basis for a new design paradigm called "Cradle-to-Grave Simulation-Based Design with Multiscale Microstructure-Property Modelling", 44 able to capture the entire life cycle of a component from casting through heat-treatment etc.…”

A literature review on methods to consider mechanical behaviour of cast aluminium alloys in finite element method (FEM) simulations of cast aluminium components has been performed. The mechanical behaviour is related to several microstructural parameters achieved during the casting process. Three different methods to consider these microstructural parameters are introduced. One method predicts the mechanical behaviour of the component using casting process simulation software. The other two methods implements numerical models for mechanical behaviour of cast aluminium into the FEM simulation. Applications of the methods are shown, including combinations with statistical methods and geometry optimisation methods. The methods are compared, and their different strengths and drawbacks are discussed.

“…Therefore, it is of interest to quantitatively characterize the cracking of such brittle constituent particles as a function of strain under different loading conditions. Such data are useful to verify the existing theoretical models for damage evolution and fracture [3,5,11], and they are required for developing and validating Internal State Variable (ISV)-based damage mechanics models for damage evolution and fracture under multi-axial loading conditions [12][13][14].…”

The utility of a novel digital image processing technique for automatic detection and separation of cracked constituent particles was applied to quantitatively characterize the microstructural damage on Fe-rich intermetallic particles that were cracked in a 7075 Al-alloy. This cracking of the Fe-rich intermetallic particles was due to a function of strain under uniaxial tension, compression, and torsion. The comparison of the data on the strained samples revealed that at tensile strain, the number fraction of the cracked Fe-rich particles was significantly higher than those at torsion while the compression strains and the average volume of the cracked Fe-rich particles increased when the strain increased. The percentage-cracked particles had a linear relationship with all of the strains for all of the loading conditions. Significant rotations of Fe-rich intermetallic particles occurred during the deformation of this alloy under torsion. These rotations tended to align themselves along the direction of applied/induced tensile stretch, which in turn affected the progression of damage due to particle cracking.
