Facilities for metallographic sample preparation and material characterization by light optical and electron microscopy techniques with hardness and microhardness capabilities. Features SEM and Light Microscopy equipment.

Contact:   Dr. John Gross


The Robert D. Stout Welding and Joining Laboratory is equipped to produce test weldments by the shielded-metal-arc, gas-metal-arc, gas-tungsten-arc, and submerged-arc processes under accurately controlled parameters of voltage, current, and travel speed. In addition, the Laboratory has facilities for preparing specimens by sawing and flame-cutting and by heating and quenching for various tests that include slow-notch-bend, hardenability, fracture-toughness, weld-restraint-cracking, implant, tension, and creep-rupture testing.

The room A140 in Imbt Laboratory is dedicated to the Computational Laboratory for Life-Cycle Structural Engineering, established in 2006.

 

It consists of:

  • Six Dell OptiPlex 990 main desktops equipped with Core i7-2600 3.4 GHz (up to 3.8 GHz) quad core processors, 8 GB of memory, and 500 GB hard drives.
  • Dual core (Intel Core2-6600 @ 2.4 GHz) desktop serving for meetings and presentation purposes.
  • Dell PowerEdge 2950 life-cycle computational server which is capable of speedily performing heavy-duty computational tasks.
  • Dell Precision workstation (T7400) with two quad core Intel Xeon E5410 processors having a clock speed of 2.33 GHz and memory of 16 GB.
  • Dell workstation (Precision R5500n) equipped with two six cores X5675 Intel Xeon processors with 3.06 GHz clock speed, 24 GB DDR3 Memory, Dual 256 MB NVIDIA Quadro graphics card, dual redundant power supply, and two 500 GB-7200 RPM hard drives.

The interaction among the computational tasks used in life-cycle analysis/prediction and the integrated life-cycle management framework are presented below.

The Intelligent Structures Laboratory (ISL) is focused on research and education in the areas of wireless sensor networks, structural health monitoring, advanced information technology for enhancement of civil infrastructure performance, structural dynamics and vibration. The lab is equipped with state-of-the-art vibration testing, sensor networks development and calibration equipments. In addition, the lab has a small-scale shaking table (18"x18"), which is used to simulate dynamic response of civil structures and prototype testbed experiments.
