ABSTRACT:
A structural beam or flexural member, supported only at its ends, has a load carrying capability which is proportional to the relative acceleration between the applied force(s) and the reaction force(s). In a first preferred embodiment, the upper section of the beam is made of a compressive rate-sensitive material, and the lower section of the beam is made of a homogeneous material. The compressive rate-sensitive material accommodates most of the compressive stress encountered in dynamic stress conditions. The homogeneous material accommodates most of the compressive stresses during static or quasi-static conditions and tensile stresses during static, quasi-static and dynamic stress conditions. In a second preferred embodiment, the beam has an upper section made of a compressive rate-sensitive material, a middle section made of a homogeneous material, and a lower section made of a tensile material. The compressive rate-sensitive material functions as in the first embodiment. The homogeneous material accommodates primarily compressive stresses during static or quasi-static conditions. The tensile material accommodates primarily tensile stresses during static, quasi-static, and tensile stress conditions.
