uctures, the computing time required for modeling the mechanics in an entire implant during cyclic loading is enormous. To address this issue, researchers from Amirkabir University of Technology in Tehran, Iran, and from Delft University of Technology, The Netherlands, teamed up and developed a multiscale modeling method that could resolve the modeling of fatigue loading in a real-size implant in a week-time. “For complete crack propagation modeling in a bone, the computational time would be around one week for the same computational power,” says Reza Hedayati, the first author of the study published in a recent issue of the International Journal of Fatigue (doi: 10.1016/j.ijfatigue.2018.05.006). The multiscale modeling uses microscale beam elements to model the area
