Biaxial Failure of GRP—Mechanisms, Modes and Theoriesfailure modes, which depend on material type and stress conditions. Biaxial failure theories can be represented as surfaces whose shape depend on both failure theory and the choice of single valued characteristic strengths. Experimental results suggest surfaces which are quadratic functions of the s

Damage Detection in Carbon Fibre Epoxy Structures Using Acoustic Emissioneloped for flat specimens. Those differences which were found between the plate and tube specimens can be explained by micrographical observations. The failure model, developed initially for steady loading conditions, has revealed the effect of regular unloading on the speed of damage accumulation i

Characterization of Composite Materials by Means of the Ultrasonic Stress Wave Factor approach has met with only limited success. On the other hand, the ultrasonic stress wave factor technique directly evaluates the material. Despite requiring access to only one surface of the material, the technique interrogates the material in the directions of applied load. Using the stress wave

Vibration and Elastic Stability of Polar Orthotropic Variable Thickness Circular Plates Subjected tong parameters of linearly varying thickness discs exhibiting polar orthotropic characteristics subjected to hydrostatic peripheral loading. By separating the flexural and geometric components of the structural stiffness, values of natural frequencies and critical buckling parameters can be obtained
