Computational modeling of polyurea-coated composites subjected to blast loads

Performance of Polymer-encased Concrete Walls Subjected to Blast Loads

Numerical study of the effect of polyurea on the performance of steel plates under blast loads

We present the results of our numerical simulation of the dynamic response and deformation of 1 m diameter circular DH-36 steel plates and DH-36 steel-polyurea bilayers, subjected to blast-like loads. Different thicknesses of the polyurea are considered and the effect of polyurea thickness on the performance of steel plates under blast loads is investigated. For each polyurea thickness, we have...

MULTI FRACTURE/DELAMINATION ANALYSIS OF COMPOSITES SUBJECTED TO IMPACT LOADINGS

A combined finite/ discrete element method is presented for modelling of composite specimens subjected to dynamic/impact loadings. The main task is set on developing an algorithm for simulation of potential bonding and debonding/delamination phenomena during impact or general dynamic loading conditions. In addition, full fracture analysis can also be performed. The proposed approach adopts a ge...

Frictional systems subjected to oscillating loads

If a discrete elastic system with frictional interfaces is subjected to periodic loading, the eventual steady-state response may depend on the initial condition or an initial transient phase of the loading history. In cases where shakedown is possible, it is known that it will occur for all initial conditions if there is no coupling between slip displacements and normal contact tractions, but t...

Computational modeling of coated biodegradable stents

Biodegradable stents are a promising technological development, as they temporarily support the stenotic blood vessel during its healing period, leaving no obstacle for possible future interventions and avoiding long term side effects of conventional drug eluting stents. Moreover, the biodegradable stent material forms an ideal vehicle for local drug delivery [1]. Finite element computer simula...
