Abstract:
Composite materials in engineering practice are widely used. Such materials have notable feature that are anisotropic, having different mechanical properties in different directions. Here is special attention devoted to their mechanical behavior. Small changes of preferred direction have significant influence to stress strain relations in fibre reinforced layers. Fibre reinforced medium is here treated as homogeneous transversally isotropic. Formed is Riemann-Christoffel’s equation leading to three homogeneous linear algebraic equations, from which displacements amplitudes may be determined. In such way problem may be analyzed as system of homogeneous algebraic equations. Developed constitutive relations are accommodated for complete analysis of dynamical behavior of laminates.
