| Abstract | Tank car design requirements and tank car safety research both evaluate impact conditions for a fluid filled tank. For the test conditions, the fluid is typically water or water based slurry that has an appropriate density to represent a specific lading. The pressure is commonly applied to the tank using compressed air. In analyses, the effects of the fluid are often included using computational simplifications such as adding the weight of the fluid lading to the tank mass and adding a constant internal pressure to the tank. For specific impact scenarios the effects of these modeling approximations have been analyzed to assess the magnitude of the effects on impact and puncture behavior. This paper describes analyses performed to evaluate the effects of the lading on the impact and puncture behavior of tank cars. The lading is explicitly modeled in various impact conditions to assess the behavior of the lading and the effect of modeling approximations on the dynamic response. In addition, the effects of the internal pressure and outage volume of various commodities on the puncture behavior are also analyzed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
