Novel energy dissipation devices for enhanced load/displacement and energy absorption

申请人将通过理论、实验和数值方法研究新型消能结构的发展。 将重点放在实验研究上。 新型消能装置包括泡沫填充编织管和轻质铝和高强度钢挤压件的切割变形。 泡沫填充的编织管可用于由于拉伸载荷而需要能量耗散的应用中，而挤出切割变形适用于压缩载荷。 这些装置可用于广泛的应用中，其可包括汽车、军事、航空航天和个人安全保护装置行业。 这些装置的一个新颖方面是能够针对特定应用调整负载/位移响应。 因此，可以在非常广泛的行业中使用。 这些装置应用的最重要方面将是降低由于福尔斯坠落、汽车碰撞、行人碰撞、爆炸或炸弹爆炸造成的伤害或死亡的可能性。

The applicant will investigate, through theoretical, experimental and numerical methods, the development of novel energy dissipation structures. An emphasis on experimental investigations will occur. The novel energy dissipation devices include foam filled braided tubes and cutting deformation of lightweight aluminum and high strength steel extrusions. Foam filled braided tubes could be utilized in applications which would require energy dissipation as a result of tensile loading while extrusion cutting deformation is applicable to compressive loading. These devices may be used in a broad range of applications, which may include automotive, military, aerospace, and personal safety protection device industries. A novel aspect of these devices is the capability of tuning the load/displacement response for specific applications. Hence, use in a very wide range of industries is possible. The most significant aspect of the application of these devices will be to reduce the severity of injuries or potential of death as a result of falls, automotive crashes, pedestrian impacts, blasts, or bomb explosions.
