Reliability Analysis of Composite Structure Using ANSYS Software

ANSYS software has provided complete and accurate solutions for composite laminate analysis and provided a set of special elements for different composite structures such as laminated plates, beams, solid structures and stiffeners. Fiber composite materials have been widely used to critical components of aircrafts, automobiles, mechanical, and marine structures. Since uncertainties associated with geometric tolerances, material properties, and boundary conditions widely exist in practical engineering problems. The probability approach is the most popular way to quantify uncertain parameters and perform the reliability analysis. The paper researches on the reliability analysis of the composite panels using ANSYS software. The numerical example is given, it is shown that the response surface method (RSM) can reduce the computational efforts comparing with Monte Carlo simulation (MCS).
