Experimental Testing and Numerical Modeling of Soil-Filled Concertainer Walls

K. Scherbatiuk and N. Rattanawangcharoen

This study uses a finite element model to predict the behavior of soil-filled concertainers under blast loading. The model's results are validated against full-scale experimental data to ensure accuracy and provide insight into the failure mechanism of the protective structures.

Shape Memory Alloy and Micro-Motor Activated High Pressure Optical Cell for Bio-Physical Studies

Oliver Hongchun Xie

This paper details the design and testing of a new shape memory alloy-based actuator for high-pressure optical cells. The actuator is developed to allow for the mixing and stirring of solutions under pressure without obstructing optical observation.

Load Impact on Railway Track Due to Unsupported Sleepers

A Lundqvist, T Dahlberg

This paper presents a computer model by which the dynamic train/track interaction can be simulated. The influence of one or several voided sleepers on the train/track interaction force and on the track dynamics is investigated. Track settlement due to hanging sleeper(s) is discussed.

Global Structural Analysis of the Response of WTC Building 7 to Fires and Debris Impact Damage

This report analyzes the structural collapse of World Trade Center Building 7 (WTC 7) due to fire-induced damage and debris impact following the 9/11 attacks. Using finite element modeling, the study examines thermal expansion, column instability, and progressive collapse mechanisms, providing insights into high-rise structural failures and fire safety improvements.
