Investigating the influence of delamination on the stiffness of composite pipes under compressive transverse

Sattar MALEKI, Roham RAFIEE, Abolfazl HASANNIA, Mohammad Reza HABIBAGAHI

Frontiers of Structural and Civil Engineering 2019, Volume 13, Issue 6,   Pages 1316-1323 doi: 10.1007/s11709-019-0555-1

Abstract: The effect of delamination on the stiffness reduction of composite pipes is studied in this research. The stiffness test of filament wound composite pipes is simulated using cohesive zone method. The modeling is accomplished to study the effect of the geometrical parameters including delamination size and its position with respect to loading direction on stiffness of the composite pipes. At first, finite element results for stiffness test of a perfect pipe without delamination are validated with the experimental results according to ASTM D2412. It is seen that the finite element results agree well with experimental results. Then the finite element model is developed for composite pips with delaminated areas with different primary shapes. Thus, the effect of the size of delaminated region on longitudinal and tangential directions and also its orientation with respect to loading direction on delamination propagation and stiffness reduction of the pipes is assessed.

The Arithmetic of GTEM Cell Axe-shaped Piece´s Side Curve Equation

Zhou Xu

Strategic Study of CAE 2003, Volume 5, Issue 9,   Pages 36-38

Abstract:

To be convenient for machining, the conventional axe-shaped pieces were approximately designed. It is proved that the traditional transition in a GTEM Cell can not give a satisfactory transmission loss distribution. So this paper gives the exact continuous curve equation for the axe-shaped piece´s two sides for the first time.
