Análisis de pandeo en laminados sometidos a cargas biaxiales utilizando probetas cruciformes

This study presents the compression-compression test with cruciform specimens (test CC) as a viable methodology to assess the geometric instability of a ±45° symmetric laminate. The central region of the specimen, subjected to biaxial loading, exhibits a geometry similar to that of a square plate fi...
