Crash tests of tension bolts in light safety collision devices
No full textThis paper demonstrates the jig set for the crash test and the crash test results of the tension bolts with respect to an applied pre-tension. The tension and shear bolts are adopted at Light Collision Safety Devices as a mechanical fuse when tension bolts reach designed failure load. The kinetic energy due to the crash is absorbed by secondary energy absorbing devices after the fracture of tension bolts. One tension bolt was designed to be failed at the load of 375 kN. The jig set was designed to convert a compressive loading to a tensile loading and installed at the high speed crash tester. The strain gauges were attached at the parallel section of the tension bolts to measure the level of the pre-tension acting on the tension bolts. Crash tests were performed with a barrier whose mass was 250 kg and initial speed of the barrier was 9.5 m/sec. The result includes the load response of the tension bolts during both the crash tests and finite element analysis

Characterization of dynamic tensile and shear strength of safety bolts in light collision safety devices of a train
No full textThis paper introduces design strategy to develop safety bolts in the light collision safety devices under dynamic tensile and shear loading conditions. The light collision safety device is an energy absorbing one for low speed collision of a train. An energy absorbing scenario in the device has several sequential stages. Tension and shear bolts are the key components which make the sequential energy absorbing scenario operated by a series of failures at the specific collapse load. Exact failure loads of tension and shear bolts at crash conditions were determined in aid of finite element analysis considering the dynamic material properties of component materials. Failure loads of tension and shear bolts designed were verified with experiments using tension and shear type jig sets at quasi-static and dynamic loading conditions. Strain gages were attached to both the parallel section of tension bolts to measure the load response acting on tension bolts and the jig set to measure the load responses acting on shear bolts. The quasi-static and dynamic experiments as well as the numerical analysis explained above predicted the load capacities of tension and shear bolts accurately for the crashworthiness design

No full textT.S. Eliot : a bibliography of T.S. Eliot criticism, 1987-2013
No full textThis bibliography of scholarship related to the writer T.S. Eliot is arranged chronologically by year and alphabetically within each year. This bibliography contains 1624 entries. Select entries have been annotated. Where available, annotations have been taken from the research database and are enclosed in brackets ([ ]). Annotations that have been taken from the works themselves are enclosed by asterisks. Annotations written by the author of this thesis have no special characters to distinguish them from other annotations. An annotated bibliography of Eliot criticism is essential to keep up with the recent resurgence in Eliot studies. The last bibliography published regarding Eliot's works was Sebastian Knowles and Scott A. Leonard's T.S. Eliot: Man and Poet, Volume 2: An Annotated Bibliography of a Decade of T.S. Eliot Criticism, 1977-1986. This new bibliography creates a central location for Eliot research for the years of 1987-2013

In search of genius: T.S. Eliot as publisher
No full textThe article discusses about the literary style of the author T.S. Eliot. A systematic examination of T.S. Eliot's interactions as a publisher with almost every aspiring poet of his time is yet to be undertaken. Such an examination would be of interest for two reasons. It would reveal more about the creative and critical principles with which Eliot himself worked and it would give some indication of the manner in which he molded English literary culture by introducing and sponsoring younger poets
