The lack of long-term performance and durability data of composite piles is an important concern that must be addressed to permit confidence in use of these piles for long-term load-bearing applications. Consequently, a durability study was undertaken to assess the rate degradation of mechanical properties (strength and stiffness) of commercially available glass fiber reinforced polymer (GFRP) ...

This paper describes the fracture mechanics approach behind the water pressure ‘blow-off test for characterising the failure behaviour of composite repairs on steel tubes. The technique enables the fracture toughness of the metal/composite interface to be determined at the point where failure initiates. Surprisingly the values found for the interfacial fracture toughness are typically an order ...

AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...

This paper provides explicit analytical expressions for displacement and stress fields in a multilayered composite cylinder with cylindrically orthotropic layers subjected to homogeneous boundary conditions. The solutions are derived in the assumption of perfect bonding between layers. The components of displacement, strain and stress are expressed in terms of the integration constants found fr...

An experimental apparatus designed to study firefighter safety equipment exposed to a thermal environment was developed. The apparatus consisted of an elevated temperature flow loop with the ability to heat the air stream up to 200°C. The thermal and flow conditions at the test section were characterized using thermocouples and bi-directional probes. The safety equipment examined in this study ...

Our research investigated the energy absorption characteristics of chiral auxetic lattices filled cylindrical composite tubes subjected to a uniaxial and lateral quasi-static load. The lattice structures were manufactured using 3D printing technique. Carbon fiber without filler material initially crushing same types experiment then performed on tubes. For different cases, load–displacements cur...

Plate impact experiments are a powerful tool in equation of state development, but are inherently limited by the range of impact velocities accessible to the facility. In an effort to dramatically increase the range of pressures which can be studied with available impact velocities, a new experimental technique is examined. The target plate is replaced by a composite assembly consisting of two ...
