A Non Contact Facility For Measuring Irreversible Energy, Residual Stress, and Full Field Stresses for Critical Rail Infra-Structure Assessment

为了实现2002年绿色文件中阐述的国家铁路目标，迫切需要具备以下能力：i）先进的（铁路）原型评估，ii）快速评估铁路基础设施，iii）提高现有（铁路）基础设施的能力。为了解决这个问题，我们提出了一种既有耗散能量测量又有“锁定”热成像能力的设施。最近澳大利亚在热弹性方面的发展使研究人员能够扩展该设备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出独特的研究能力。

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.
