frequently, many array elements cannot be set due to environmental conditions. One-dimensional azimuth estimation generally used the time delay method [19] and beam forming method [20], but this method......
in the conventional process of the long samples. Critical force for buckling of the punch (Pcr) is like the simply supported beam, which is calculated from Eq. (5). (5) where E is the elastic modulus of punch, I......
