Damage Tolerance of Composite Materials Subject to Dynamic Flexural Tests

Modeling of Hygrothermal Damage of Composite Materials

Composite materials have been used extensively in various applications, such as mechanical engineering, aerospace engineering, and aviation thanks to their interesting mechanical properties. However, a substantial drawback in the use of such composite materials is that they absorb a significant amount of moisture when exposed to severe hygrothermal conditions. This factor dramatically affects t...

Damage evolution in particulate composite materials

Damage evolution in heterogeneous solids is modeled using transformation field analysis and imperfect interface model. Stress changes caused by local debonding are simulated by residual stresses generated by equivalent transformation strains or eigenstrains. Decohesion and both overall and local stress and strain rates are derived from thermodynamics of irreversible processes, which provide an ...

Damage tolerance and residual strength of composite sandwich structures

Damage Detection of Composite Materials with LAMB Wave Method

The aim of the experimental study described in this paper was Lamb wave method evaluation for damage/ defects detection of epoxi/glass composites. Can be used piezoelectric transducers actuator/sensor glued on the surface of investigated composite, using transmission mode. The chosen control parameter was the sensor signal attenuation because of defects that exists in examinated samples. The pr...
