A wide column test of a composite isogrid panel subjected to quasi-static, axial compression is modeled with a hybrid-static dynamic computational method. The data from the test panel exhibited discontinuous responses in the compressive load for slowly increased end-shortening. The computational model was developed to corroborate these discontinuities with the phenomenon of mode jumping. Mode j...

Based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (FG-CNTRC) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. In the process, stress and displacement fields are expanded according to the Fourier series along the axial and circumferential coordinates. From ...

Honeycomb sandwich panels can reduce weight, and particular strength needs are crucial to the modern aerospace industry. The principal benefits of honeycomb include rigidity, stress absorption, fatigue resistance, resistance weather, chemicals, fire isolation. Today, choosing a design with cheap recyclable core material is common due mechanical acoustic requirements high weight target. Aeroplan...
