Fatigue behavior of impacted composite structures

Thermoauxetic Behavior of Composite Structures

This paper presents a study of new two-dimensional composite structures with respect to their thermomechanical properties. The investigated structures are based on very well-known auxetic geometries-i.e., the anti-tetrachiral and re-entrant honeycomb-modified by additional linking elements, material which is highly sensitive to changes of temperature. The study shows that temperature can be use...

Fatigue Delamination Monitoring in Composite Structures by Guided Wave Method

This paper presents an effective parameter for fatigue delamination detection and monitoring by guided wave method. The finite element analysis and the Time of Flight parameter defined as a time between guided wave interrogated by an actuator and first wave captured by a sensor was introduced to observe the behaviour of the defected structure. The relationship between ToF and delamination size ...

Deformation Characteristics of Composite Structures

The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...

The Effect of Geometrical Parameters of Cylindrical Composite Lattice Structures on Buckling Behavior

Due to their light weights and high load carrying capacities, composite structures are widely used in various industrial applications especially in aerospace industry. Stiffening ribs are the main features of lattice type composite structures. Strength to weight ratio is known to be as one of the most critical design parameter in these structures. In this study, the effect of some parameters su...
