PY - 2020/10/24 Y2 - 2026/03/21 TI - Computational Design of External Breast Prothesis According to Physical Properties of Elastomeric Materials JF - Memorias del Congreso Nacional de Ingeniería Biomédica JA - MCNIB VL - 7 IS - 1 SE - Concurso Estudiantil DO - UR - https://www.memoriascnib.mx/index.php/memorias/article/view/802 SP - 493-500 AB - <p>This paper presents a computational design for an external breast prosthesis by means of a finite element analysis (FEA) according to theoretical physical properties of an elastomeric material. The first 3D model design was created using anthropometrics dimensions of a woman and a CAD software. Afterwards the model was analyzed through FEA and computational simulations based on mechanical loads applied to the prosthesis during the daily activities of a woman and on the physical properties of the elastomeric material selected, in this case, the polydimethylsiloxane (PDMS). The performance evaluation of the prosthesis was made following the Mooney-Rivlin mathematical model for elastomers. The 3D design obtained with displacements and distribution of stress due the loads applied, could be prototyped by 3d printing process or a molding process to make an external breast prosthesis that mimics to a real breast.</p> ER -
