Numerical Modeling of Earthquake-Induced Ground Deformations
Professor Katerina Ziotopoulou
Non-linear dynamic analyses (NDAs) are widely used in engineering practice to evaluate the seismic performance of geotechnical structures affected by liquefaction or cyclic softening.
Full-Scale Five-Story Building Shake Table Test
Dr. Michelle Chen
Intense earthquake ground motions can be devastating to communities, and can lead to years and even decades of recovery. It is observed in recent earthquakes that nonstructural components, which make up a large part of a building’s cost, are vulnerable to seismic damage.
Materials and Processing for Aerostructures, Emerging Technologies and Future Needs
Dr. Teresa Kruckenberg
This presentation will cover the conventional materials, processing and design applications for aerostructures such as nacelles and flight control surfaces. Examples of emerging technologies such as additive manufacturing, nanomaterials, prognostic health management, ultra-
This work presents a method for uncertainty propagation that is consistent with the “building-block approach” in which components of a system are tested and validated individually instead of an integrated vehicle test and validation being performed.
Analyze Uncertainties Associated with GMPE for PSHA
Dr. Chin-Hsiung Loh
In probabilistic seismic hazard analysis (PSHA), the standard practice is to se¬lect a set of appropriate ground motion prediction equations (GMPEs) and assign weights on the logic tree, especially for regions where strong motion data are sparse and where no indigenous GMPE exists.
Uncertainty Quantification of Complex Systems via Multi-fidelity Modeling
Professor Alireza Doostan
Realistic analysis and design optimization of complex engineering systems require not only a fine understanding and modeling of the underlying physics and their interactions but also recognition of intrinsic uncertainties and their influences on the quantities of interest.
This seminar is intended to highlight current industry standards for performing nondestructive testing (NDT) by presenting several case studies from recent project work. Techniques included ground-penetrating radar, ultrasonic tomography, ultrasonic pulse velocity, acoustic emissions and impact echo will be discussed.…
The Failure Forecast Method as a Prognostic Extension of Structural Health Monitoring
Professor Michael Todd
Damage prognosis is the act of making an informed prediction of the future state of health of a system or component, given that a current diagnostic state is available with its uncertainty quantified. It has been noted that several material failure modes occur, after initiation phases, as a consequence of a positive-feedback mechanism.…
Fire Protection Engineering- What it is and Why You Should Care
Garner A. Palenske
Fire protection engineers use math and science to protection people from the risk of fire and explosions. The practice is based upon the fundamentals of heat transfer, thermal dynamics, and structural mechanics.
Field Responsive Mechanical Metamaterials
Mechanical metamaterials possess previously unobtainable structural mechanical properties, primarily derived from their underlying three-dimensional (3D) architecture.
