Improvement of vibrational characteristics of multipurpose structures (plate and shells) used in aerospace components by deploying Graphene Oxide Powders (GOPs) in a matrix as a nano-reinforcement: A comprehensive study

Guided Wave-Based Damage Detection of Square Steel Tubes Utilizing Structure Symmetry

“…Ultrasonic guided wave (UGW) is a kind of ultrasonic wave that can propagate in structural members with finite boundaries, such as thin plates [2][3][4][5][6][7][8][9], tubes [10][11][12][13][14][15][16], bars [17], other member types [18][19][20]. When encountering small defects or damages in structures, wave scattering and reflection will occur.…”

“…With regard to the damage detection of square steel tubes using UGWs, Wan [1] investigated frequency dispersion characteristics and selected the appropriate guided wave mode to inspect through-hole and slot damages. Ultrasonic guided wave (UGW) is a kind of ultrasonic wave that can propagate in structural members with finite boundaries, such as thin plates [2][3][4][5][6][7][8][9], tubes [10][11][12][13][14][15][16], bars [17], other member types [18][19][20].

Buckling analysis of laminated composite elliptical shells using the spline finite strip procedure

“…Elastic instability (buckling) phenomena could be a shape of flimsiness that happens in a flexible framework, such as buckling of pillars and pieces subjected to compressive loads. Due to the high application demand, shell-type structures, particularly, cylindrical shells having superior mechanical characteristics and excellent high strength performance are applied widely in many engineering problems such as aerospace [ 8 ], nuclear reactors [ 9 ], the marine industry [ 10 ], civil engineering [ 11 ], and mechanical engineering [ 12 ]. So far, numerous researches investigated the buckling behavior of shell-type structures.…”
