To meet the national rail objectives as enunciated in the 2002 Green Paper there is an urgent requirement for a capability for: i) advanced (rail) prototype assessment, ii) rapid assessment of rail infra-structure, iii) for increasing the capacity of existing (rail) infra-structure. To address this we propose a facility with both a dissipative energy measurement and a 'lock in' thermograpghy capability. Recent Australian developments in thermo-elasticity enables the researchers to extend this facility to measure residual stress in complex components. The ability to measure dissipated energy, residual stress, ultrasonic waves, and full field stress will create a unique research capability.

为了实现 2002 年绿皮书中阐述的国家铁路目标，迫切需要以下能力：i) 先进的（铁路）原型评估，ii）铁路基础设施的快速评估，iii）增加现有（铁路）基础设施的容量。为了解决这个问题，我们提出了一种具有耗散能量测量和“锁定”热成像功能的设施。澳大利亚最近在热弹性方面的发展使研究人员能够扩展该设施以测量复杂部件中的残余应力。测量耗散能量、残余应力、超声波和全场应力的能力将创造独特的研究能力。
