Hybrid polymeric composites are gaining important consideration with versatile applications due to their good mechanical properties. The present study is an attempt to evaluate the hybridization effects of different laminate stacking sequence involving areca sheath fiber/jute fiber/glass-woven fabric through the study of mechanical properties of four different resulting composites. The fibers were alkali-treated and were used in composites fabrication that was done using the hand lay-up method. This assessment of mechanical properties and study of fractured surfaces indicated a significant improvement in mechanical properties of the composites with jute fiber as intermittent layers, areca sheath fiber as a core layer, and glass fabrics as skin layer reinforced epoxy composites. An attempt to prove the application suitability of “L” frame for flower stand application was fabricated using the best mechanical behavior performer composite, and the ANSYS (deformation) analysis was also performed.

The discrete solid element method is an efficient numerical method that simulates the large deformation, strong material nonlinearity, fracture, and dynamic problems of continuity. In the discrete solid element method model, the spring stiffness of the spherical elements on the boundary is different from that inside the discrete solid element method model based on the principle of conservation of energy. The spring stiffness of the spherical elements on the boundary of the discrete solid element method model is shown to have a significant effect on the macroscopic properties. According to the position of the spherical elements on the boundary of the discrete solid element method model, the spherical elements on the boundary are divided into three types, which are spherical elements on the surface position, on the edge position, and on the corner position. To accurately reflect the mechanical behavior of the material, the principle of energy conservation is used to strictly deduce the spring stiffness of the three types of spherical elements on the boundary, and the relationship between the spring stiffness and elastic constants is established. The numerical example shows that the calculation accuracy of the discrete solid element method in modeling the mechanical behavior of continuity is improved after the spring stiffness of the spherical elements on the boundary is revised. In addition, the applications of the discrete solid element method to dynamic buckling of the thin plate and buckling of the cracked thin plate are also given.
