The commercial finite element program LS-DYNA was employed to evaluate the response and energy absorbing capacity of cylindrical metal tubes that are externally wrapped with composite. The effects of composite wall thickness, loading conditions and fiber ply orientation were examined. The results demonstrate that a wrapped composite can be utilized effectively to enhance the crushing characteri...

The use of aluminum alloys for external strengthening reinforced concrete (RC) beams has been capturing research interest. Exposure to harsh environmental conditions can severely impact the efficiency. This works aims investigate degradation in mechanical properties alloy AA 5083 plates when exposed temperatures ranging from 25 300 °C. Quasi-static Isothermal tensile experiments were conducted ...

A self-healing, metal matrix composite reinforced by shape memory alloy wires is simulated using finite element analysis. A one-dimensional constitutive model for SMA behavior is implemented as a user-defined truss element in ABAQUS. The matrix is brittle and a mode I crack is allowed to propagate through the specimen upon loading. During the loading process the wires undergo a martensitic phas...

A regulatory framework is required to ensure the correct design of Fibre-Reinforced Polymers (FRPs) increasingly being used as an externally-bonded strengthening system on concrete columns. Several guidelines confinement FRP have been developed over past few years worldwide, each proposing a different approach, resulting in predictions. This study aims evaluate and compare nine international pr...

Externally bonded carbon-epoxy fiber-reinforced polymers (CFRPs) have been widely used to restore or increase the capacities of reinforced concrete beams (Meier et al., 1992; Neale and Labossière, 1997; Varastehpour and Hamelin, 1997). A typical reinforced concrete bridge deck may experience up to 7x10 stress cycles during the course of a 120year life span (Barnes and Mays, 1999), while an over...

This paper presents an extensive experimental and numerical study on the behavior of CFRP/Steel adhesively bonded double strap joints (DSJ). A total 50 DSJ specimens were tested under static tensile loading. The digital image correlation (DIC) was used to measure backface deformation. six adhesives that feature different stiffness, strength, ductility, toughness analyzed. parametric including s...
