In this paper we consider stiffness properties of square symmetric unidirectional two-phase composites with given volume fractions.
The next corollary provides an example of stability result for the functional equation of homomorphism for square symmetric groupoids, which corresponds to some outcomes in [18, 42 44].

Joe et al. investigated the simultaneous multiple cross-ion irradiation on the Au (100) and observed the formation of square-symmetric nanoholes and nanodots [32].
In this work, by means of a novel and fast implementation of the Bidirectional Evolutionary Structural Optimization technique, shape optimization is conducted on the hole shape obtaining several topologies, also with non-square-symmetric unit cell, endowed with complete 3D full bandgaps for in-plane waves.
A lot of topologies can be found in the literature for PnCs with square-symmetric unit cell that exhibit complete 2D bandgaps; however, due to the application demand, it is desirable to find the best topologies in order to guarantee full bandgaps referred to in-plane wave propagation in the complete 3D structure.
A relevant prior belief in this case might be that a square is symmetric about a diagonal.
Four typical leading edges used in various engineering applications were studied in this work: the semi-circular, square, 30∘ symmetric trapezoid and 30∘ asymmetric trapezoid leading edges.
