in hypermesh software was used to characterize the mechanical behavior of bone tissue [ 16 ], and the cowper-symonds model was used for strain rate, which represented the yield stress through parameters related to strain rate. the failure is defined by setting a failure plastic strain in bone...
(a) specimen ofIguana iguanaused for CT-scan and for subsequent dissection in order to model muscle origin attachment areas. (b) 3D volume mesh model ofI. iguanaused for the FEA and with muscles maps. (c) Muscle attachments in lateral aspect. (d) Muscle attachments in anterolateral aspect....
The cleaned mesh was modified in Geomagic Studio 12 to produce two hypotheti- cal models: one with a complete lower temporal bar, and one with an incomplete lower temporal bar attached by a ligament to the quadrate. The ligaments in all models were represented by sets of tension-only ...
Optimal body structure design is a central focus in the field of passive automotive safety. A well-designed body structure enhances the lower threshold for crash safety, serving as a basis for the deployment of other safety systems. Frontal crashes, part
In the subsequent phase, the contours delineating the cortical bone, cancellous bone, teeth, and brackets (see Figure 1d) were populated with a mesh of 3D elements using the Hypermesh system (Altair, Troy, MI, USA). Tetragonal elements were selected for this purpose. Taking advantage of the...
