Project outline:

Metal foams are a class of lightweight, micro-heterogeneous materials with novel mechanical, thermal, and acoustic properties. From a mechanical standpoint, the high strength, stiffness, and energy absorption of metal foams have made them popular in various structural applications, ranging
from foam-filled beams and columns to crash-absorbing elements in the automotive industry. Recently, numerous studies have been conducted to numerically predict the behavior of metal foams and hybrid metal foams. The primary focus of this project is to integrate the finite cell method (FCM) with the phase field approach to predict the damage and fracture behavior of metal foams. The identification of micro-material parameters of the metal foams is achieved by applying FCM phase field models to the real pore geometries of metal foams. In certain cases, finite element analysis will also be employed to compare the results obtained from FEM and FCM.
