The Form and Function of the Kolsky Bar for Dynamic Three-Point Bending,spectrum of strain rates. Patch repairs on roadways and bridges experience long-term fatigue and environmental loading. Such repair jobs can experience pure compressive or tensile stresses, while others experience large shear and bending stresses. The same is true for composite armors, which can exp

Ballistic Performance Evaluation of Carbon Graphite Foam (CGF) and Nanoparticle-Kevlar (SNK) Compos) are of interest in many multifunctional applications. It is therefore desirable to evaluate their ballistic performance in comparison to baseline foams or untreated Kevlar, for instance. In this study, we evaluate CGF and SNK composite samples using compressed-air guns (CAG). Two CAGs are used in

Shear Damage Model Identification for Off-axis IBII Composites Specimen Loaded and Unloaded at High wave speed and low strain to failure. Moreover, it is well known that such composites exhibit a non- linear response in shear generally attributed to a combination of damage and matrix plasticity. In quasi-static conditions, such models are generally identified by performing cycles of loading and u

The challenge with using Hopkinson tubes is that the force determined from the traveling stress wave in many cases does not match the contact force causing the d

A,ty combinations are investigated. CFRP samples are also subjected to impact at room temperature (23 °C) and low-temperature (−70 °C) conditions with the aim to understand composite behavior in cold Arctic environment. Furthermore, this study explores the effect of ice formed on substrate surface, so

Structural adhesives are particularly valuable for joining dissimilar materials, bonding composite materials, and light-weighting structures in transportation in order to minimize energy consumption. These applications also require structural adhesive bonds to provide satisfac
