Thin-walled cylinders are sensitive to imperfections

Decreased buckling loads and geometrical imperfections are closely related for thin-walled cylinders. By definition, a geometrical imperfection is a deviation from the perfect cylindrical geometry. An example is shown in Figure 1. Geometrical imperfections have been demonstrated to have clearly … Read More

Making a laminate twist

The properties of fiber-reinforced composite structures can be tailored with layer orientations and stacking sequence. For example, you can design your laminate so that under a tensile load it twists, but at the same time it does not bend nor … Read More
