Abstract
Composites materials are now being used in primary
aircraft structures, and other domains because of numerous advantages. A
part of a continuous in-flight operating costs, gas turbine engine
manufacturers are always looking for ways to decrease engine weight. This is
the case of compressor blades which have to satisfy, for example, the
standard bird strike or debris in order to measure the crashworthiness. Bird
strike impacts are actually among the most challenging loads that composite
blades must accommodate. Thus for the further development of composite
structures, it becomes important to have available predictive tools for
simulating the response of composite structures under crash or impact loads,
which will allow to evaluate damage state in the structure in function of
time. A composites damage model, without mesh dependency, is presented, and
allows to obtain agreement with impact experiment. Examples of finite
element simulations for the impact response of blade based on this materials
model are developped. These numerical results correspond to a bird strike on
an equivalent composites blade, and insists on damage evolution in
structure.
