Development and three-dimensional morphology of the zygomaticotemporal suture in primate skulls [PDF]

open access: yes, 2014
Cranial sutures are an essential part of the growing skull, allowing bones to increase in size during growth, with their morphology widely believed to be dictated by the forces and displacements that they experience.

Flexural Behavior of Hybrid Composite Beam (HCB) Bridges

open access: yesAdvances in Materials Science and Engineering, 2019
A new hybrid composite beam (HCB) has recently been used in the construction of three bridges in Missouri, USA. HCB consists of self-consolidating concrete (SCC) that is poured into classical arch shape and tied at the ends by steel tendons.

Function-Orientated Structural Analysis of the Proximal Human Femur [PDF]

open access: yes, 2009
In his model of the biomechanics of the proximal human femur, Friedrich Pauwels assumes a resultant force acting on the femoral head that is created by the partial body weight and the force of the abductor muscles inserting at the greater trochanter ...
