Scaled models for failure under impact loading

Simulation of Reinforced Concrete Structure under Impact Loading using Meshfree Cohesive Failure Approach

Reliable numerical simulation of failure is important for the design and planning of new solids and structures, as well as for the safety assessment of existing ones. In the past two decades, gradient and non-local models for regularizing loss of ellipticity due to material failure using non-standard finite element method and more recently the meshfree method have been the topic of considerable...

Hyperelastic Behavior of Porcine Aorta under Sub-Failure Inflation Loading

While traumatic aortic rupture (TAR) continues to be a major cause of fatality in motor vehicle accidents, the underlying mechanisms of it are not well understood. A major step to gain an insight into this problem is to understand the mechanical behavior of aortic tissue under loading conditions that lead to the failure. Although the mechanical properties of blood vessels under physiological pr...

Failure of Fibrous Composite Plates under Static Biaxial Planar Loading

This paper outlines an experimental investigation carried out for the analysis of failure mechanisms in fibrous laminated composite plates containing stress raisers, in the form of cutouts, under static biaxial planar compressive loadiing. A specially designed biaxial loadiing frame was used to test a series of 48 ply graphite/epoxy composite laminated plates with centrally located circular hol...

Failure of Ab(1-40) amyloid fibrils under tensile loading

Amyloid fibrils and plaques are detected in the brain tissue of patients affected by Alzheimer’s disease, but have also been found as part of normal physiological processes such as bacterial adhesion. Due to their highly organized structures, amyloid proteins have also been used for the development of nanomaterials, for a variety of applications including biomaterials for tissue engineering, na...
