FRA has an established program to evaluate the puncture resistance of various tank car designs. This program supports examining strategies to lower the potential for loss of lading of tank cars involved in derailments. FRA seeks to develop standardized test and simulation methodologies for quantifying the puncture resistance of tank car designs. This program has previously tested DOT-105 [1][2], DOT-111 [3], DOT-112 [4], and DOT-117 [5] tank cars under similar shell impact conditions. A companion FEA is performed alongside each test, and the test results are used to both validate the pre-test model and improve future finite element (FE) models.
