A computer program is provided for the estimation of r.m.s.
surface strains in rectangular laminated skin panels. It applies to
specially-orthotropic plates having principal axes of orthotropy
parallel to the plate edges. A precise definition of this class of
plates is given in ESDU 83035. The calculation procedure is
particularly applicable to fibre-reinforced composite laminated
plates. The computer program evaluates r.m.s. strains parallel to
the shorter (or curved edge, if the plate is curved) at the mid
points of the longer edges and at the plate centre. The analysis is
a simplified normal mode method assuming a single mode
(fundamental) response but uses empirically derived correction
factors. A good correlation is shown between predictions using the
method and available experimental results extracted from the
literature. The program is provided as ESDUpac A8408.
