EL-SAYED S [4] established a cohesive layer model (CLD) to track debond growth at the interface and cracks kinking into the sandwich core.
More details about the mesh size of the interface element can be found in Turon et al [19].

Sun Tracking Tests A conventional el-azimuth mount has a problem with tracking celestial objects which are directly overhead.
This is because an el-azimuth mount typically has a range from 0 to 90°.
The ability of a hexapod to continually track objects directly overhead is an advantage which a hexapod offers above an el-azimuth mount.
