Abstract
There have been numerous research works of reliability analysis whose objectives are concerned with the evaluation of variability of characteristic features of composite materials. Most of these are based on the modelling analysis from the viewpoint of micro yielding behavior or crack propagation phenomena under the idealized condition such as uniaxial tensile load. Though they contribute to clarify the micro behavior of failure phenomena and strength variabilities and to find what is the most sensitive factor among various factors, they can not construct the method of materials design. One of the major objectives of this paper is to discuss some problems for stochastic materials design of composite laminate with material characterization as modulus, lamination angle, various strengths under the generarized load condition.
