J. Jackson, Battelle Columbus Labs, Columbus, OH
Battelle has been involved with data acquisition and analysis for design allowables for metallic materials used by the aerospace industry since the 1950’s starting with ANC-5, which became MIL-HDBK-5, and has been superceded by the current MMPDS (Metallic Materials Properties Development and Standardization) Handbook. Data is acquired from various producers and users. Battelle provides an un-biased analysis result. Data types include both static and dynamic properties such as; tensile, compression, bearing, shear, effect of temperature, stress-strain curves, creep-rupture, and fatigue. Several tools have been and are being prepared for analysis use. These tools incorporate the analysis guidelines of MMPDS (and former MIL-HDBK-5). A recent project with Boeing, ASM and others showed the feasibility of using electronic data transmittal using MatML language for greater efficiency of data transmittal to the software tools. Use of a common data transmittal form or language will increase the efficiency of data analysis process and data storage. This also provides a single method to transmit data in the handbook to the licensees which may have different input formats. Two of the tools will be demonstrated; ISG software analysis for static design allowables and an ISG stress-strain analysis tool. These tools have been created in conjunction with ISG (Industry Steering Group) funds and are available to ISG members on the MMPDS website. More information on membership may be obtained at

Summary: Battelle has been involved with data acquisition and analysis for design allowables for metallic materials used by the aerospace industry since the 1950’s. Use of a common data transmittal form or language will increase the efficiency of the data analysis process, the data storage, and the transfer of data results. Two of the data analysis tools will be demonstrated.
