Project Description Interface materials between the body and external supports play a consequential role in determining the mechanical loading that the body will experience. Intensive and prolonged mechanical loading (pressure, shear) at body interfaces can cause soft tissue damage and chronic wounds, i.e. pressure ulcers, which can affect quality of life for many patients in the general field of prosthetics and orthotics (P&O), including prosthetic socket interfaces and special seating for wheelchair users. Typically, soft elastomer foams are used as cushioning interface materials to help distribute loading and reduce the levels of pressure and shear that can lead to damage and injury. This project will focus on mechanically characterising porous materials under combined pressure and shear loading to determine the effect of complex combined loading on mechanical response, and thus load transfer to soft tissue in the body. Additive manufacturing (a.k.a. 3D printing) techniques will be used to manufacture porous elastomer materials with controlled pore geometry in order to assess the effects on combined mechanical properties and inform the design of better interface materials that can help to prevent tissue damage and injuries.

项目描述身体和外部支撑之间的接口材料在确定身体会体验的机械负载方面起着相应的作用。在人体界面处的强化和长时间的机械负荷（压力，剪切）会导致软组织损伤和慢性伤口，即压疮，这可能会影响许多患者的生活质量，包括普通话和矫形器（P＆O），包括假体插座插座界面以及轮椅使用者的特殊座椅。通常，软弹性体泡沫用作缓冲界面材料，以帮助分配负载并降低压力和剪切水平，从而导致损伤和受伤。该项目将集中于在组合压力和剪切负荷下机械表征多孔材料，以确定复杂的组合负荷对机械响应的影响，从而确定载荷转移到体内软组织中。添加剂制造（又称3D打印）技术将用于制造具有受控毛孔几何形状的多孔弹性体材料，以评估对合并机械性能的影响，并为更好的界面材料设计，以帮助防止组织损伤和伤害。
