2. Analytical modeling
A debonded curved sandwich beam of arc-length L and width b
is illustrated in Fig. 1. The beam consists of a core of height c and
two facesheets of thickness dt and db. The subscripts t, b and c stand
for the top and bottom facesheets and the core, respectively. The
kinematic relations of the facesheets are supposed to follow the
EulereBernoulli curved beam theory
