Graded/gradient porous biomaterials
WebThis paper is concerned with the multi-objective optimization of thickness-wise CNT distribution in functionally graded porous CNT-reinforced composite (FG-porous CNTRC) beams. The mechanical behaviors of FG-porous CNTRC structures are strongly influenced by the thickness-wise distributions of CNTs and porosity. Nevertheless, several linear … http://article.ajnanosciences.org/pdf/10.11648.j.ajn.20240402.11.pdf
