Thin-walled hollow structures have the stiffness and low weight, but they can have other characteristics that lower machine performance. For example, if the natural frequency of a beam or its ...

Seat frame demonstrates next-generation autocomposites design Light weight, simplified/cost-effective manufacturing, passenger comfort and safety informed materials and process innovations and won ...

Tough I-beam bridge for tank traffic Immiscible polymer blending combines the strength of HDPE and the stiffness of glass-reinforced PP to create I-beams with specific strength greater than steel.

The new joint design for timber-concrete composite frames significantly improves load transfer and stiffness, addressing key challenges in hybrid construction.

Vibration-absorbing, sound-damping materials such as sheets of rubber and expanded foam tend to be thick, bulky and soft. A new material is a big exception to that tendency, however, as it absorbs ...

Beam with shear stiffness Now let’s consider reconsider our laminated beam where shear stresses are produced as the laminae slide with respect to each other under loading. For example, these stresses ...

In terms of its performance, the composites beam showed very high stiffness in a temperature range from -40C to +90C.

How often did John R. Hillman, founder and president of Chicago-based HC Bridge Co., LLC, think about giving up on getting the industry to accept his hybrid bridge beam of concrete and steel with ...

Five years after a fully loaded locomotive and 26 coal cars chugged over a 30-ft-long, 17-ft-wide span comprising eight hybrid composite beams (HCB) in Colorado, the technology has been used in ...
