Stability analysis of carbon nanotube-bounded composite lamina with single crack and Oblique Support Conditions

The proposed study introduces a fresh examination of the effects of plate obliqueness and crack-related variables on the distortion behaviour of cracked carbon nanotube (CNT)-strengthened composite distort plates. A numerical model has been created in MATLAB utilising the stretch numerical approximation techniques to assess the distortion behaviour of these plates under diverse in-plane stress conditions and boundary constraints. The work methodology examines the impact of geometric variables, such as oblique angle, and crack attributes, including dimensions and positions. The Eshelby–Mori–Tanaka homogenisation method incorporates the role of monolayer carbon nanotube (CNT) content and its distribution throughout the matrix. The results indicate that structural stability is significantly influenced by plate geometry, support conditions, crack dimensions, and their placement. Moreover, non-uniform distribution or aggregation of CNTs is demonstrated to diminish the effective material rigidity and decrease the critical unstable load.
