<\/span><\/p>\n

In the manuscript, authors Iván Rivet and collegues, propose an MB cracking model that incorporates the orthotropic brittleness of FFF components<\/strong> and use experimental and numerical simulations to compare their criterion to that of Tsai–Wu (TW), which is commonly used for orthotropic materials. <\/span><\/p>\n

According to the researchers, the results of the novel MB damage criterion outperform those of TW, and can accurately match experimental outcomes<\/strong> and predict the breaking mechanism even in complex 3D states<\/strong>.<\/span><\/p>\n

In Iván Rivet’s words, this new model allows for “reduced-cost high-fidelity simulations<\/strong> of Additive Manufacturing components”, and will enable “a better understanding of their orthotropic mechanical properties and mixed failure modes”.<\/span><\/p>\n

All the research has been developed in the International Centre for Numerical Methods in Engineering (CIMNE) by Iván Rivet<\/a> (Conceptualization, Software, Writing, and Editing), Narges Dialami<\/a> (Methodology, Validation, and Review), Miguel Cervera<\/a> (Conceptualization, Supervision, and Review), and Michele Chiumenti<\/a> (Conceptualization and Software).<\/span><\/p>\n
