We give an analysis of the stability and uniqueness of the simply laminated microstructure for all three tetragonal to monoclinic martensitic transformations. The energy density for tetragonal to monoclinic transformations has four rotationally invariant wells since the transformation has four variants. One of these tetragonal to monoclinic martensitic transformations corresponds to the shearin...

In this investigation, scanning electron microscopy was used to characterize the microstructure on the surfaces of animal heart valve cusps/leaflets. The results showed that though these surfaces appear smooth to the naked eye, they are actually comprised of a double hierarchical structure consisting of a cobblestone-like microstructure and nano-cilia along with mastoids with a directional arra...

To capture all the individual microstructural effects of complex and heterogeneous materials in structural finite element simulations, a two-scale simulation approach is necessary. Since computational effort such simulations extremely high, different methods exist to overcome this problem. In terms FFT-based microscale simulation, one possibility use reduced set frequencies leading numerical so...

Cemented carbides have been known for about a hundred years and are now widely used in mining, civil road construction, mechanical engineering. Their improvement requires the development of novel technologies based on fundamentally new approaches. Here method microstructure analysis using computer processing with elements machine learning artificial intelligence is proposed. It has applied to m...
