This paper presents work done on a bolted connection in carbon-fiber reinforced polymer composite materials.
Introduction Carbon fiber reinforced polymer (CFRP) composite materials have gained widespread use in aerospace structures due to their low weight, high strength, and high stiffness properties.
Furthermore, the brittleness of composite materials coupled with the possibility of high stress concentrations due to anisotropy require special considerations when designing such connections [2].

The higher order discontinuous asymptotic fields which are similar to the Williams’ solutions of homogenous material are obtained by the displacement method and asymptotic analysis for a plane crack at the physical weak-discontinuous interface in non-homogeneous materials.
Introduction It has been widely accepted that functionally graded materials (FGMs)[1,2,3,4] is completely different from the homogeneous materials or the traditional composite materials.

Typical raw materials are mixtures of epoxy resin and Nd2Fe14B flakes, produced mostly by melt spinning.
Flake aspect is usual for materials produced by melting spinning.

Experimental Materials.
A concrete-mixer was used to mix the materials and get the concrete.
These dry materials were mixed for about 1 minute before water was added.
