|I have resisted the pressure to remain focused on one or a few research interests during my academic career, and have always sought to pursue what I perceived to be particularly interesting at a given time (a delicate balance between opportunity and interest). This has at times hurt my career, but I had fun in "escaping the reality" of academia and have always tried to think outside the box.|

Future StudentsI have historically had very few graduate students.
Minimum requirements: I would expect my graduate students to be very comfortable with Matlab and/or Mathematica, and be ready to write all reports in LaTeX and draw with Visio. If you are comfortable with Fortran, c++, Python, Unix it is a plus. I am currently looking for a student with proven laboratory skills for a project starting June 2016.
Potential Thesis Topics
Topics of interest for future independant studeis, master thesis/report or PhD thesis include:
A full list of my publications is easily found in my my resume.
- Cracking of a Nuclear Reactor Container I have lately been heavily involved in the root cause investigation of the craking on a nuclear reactor container. This involved both 3D nonlinear finite element analysis, as well as performing various tests on concrete cores recovered from the site.
- Non linear transient analysis of concrete dams: From 2000-2009 my research has been funded by the Tokyo Electric Power Service Company (TEPSCO). Within the framework of this project, we seek to develop a State of the Art finite element program (Merlin) for the 3D nonlinear, transient, multiple-CPU, analysis of concrete dams. Centrifuge tests for validations were also performed both in Boulder and Tokyo. OpenGL based pre and post processors are also being developed. (Kumo and Spider). Prior to this project, I was funded for 5 years by the Electric Power Research Institute (EPRI) to examine the applicability of fracture mechanics to concrete dams. Much of this researchon dam safety is summarized in http://www.dam-analysis.com.
- Fast Hybrid Testing: From 2005-2009 I directed and managed the CU-NEES site. Following the closure of the site, I supervised the development of development of Mercury, a software to facilitate single site, hybrid simulation through serial or parallel computers, and taking advantage of innovative hardware such as FPGPA)
- Currently testing a reinforced concrete frame previously tested on a shake table. Another component is to explore the applicability of FHT to aerospace vehicle testing.
- Fracture of concrete: Over the years, I have conducted numerous innovative and large scale tests to examine the fracture properties of concrete. These include: large wedge splitting tests (1.5x1.5 m and 7.5 cm MSA); Static and Dynamic fracture properties; Static and dynamic fluid pressure inside cracks; Fatigue crack propagation; Fracture of joints subjected to both static and cyclic loads. In practically all cases tests were first performed, a theoretical model was then developed, and finally a finite element code (MERLIN) was then modified to implement the model and test it.
- Fracture of Solid Rocket Propellants Through a collaboration with a German company, we have tested the fracture energy of solid rocket propellant, then modeled the cracking of the propellant in a rocket, and are currently developing a code which couples combustion simulation with fracture mechanics.
- Fracture of rocks: Tested soft rock (Tuffo), and planning to apply those test results to the analysis of cave stability in Naples (with Prof. Viggiani/Grenoble).
- Fracture of Ceramics: (with Prof. Sbaizero) performed numerical simulations of ceramic fractures by applying concrete nonlinear models.
- Fractal analysis: Performed some early tests to determine the fractal dimension of cracked concrete, extended the size effect law to account for fractal cracks.
- Alkali-Aggregate Reactions: Developed a constitutive model for concrete undergoing AAR. Implemented the model in MERLIN and then performed 3D analyses of both dams and massive reinforced concrete strucutres. Designed, built and tested a triaxial frame to subject a concrete cube undergoing an AAR to a constant pressure, temperature and humidity, and then measure expansion in the three directions.
- Chloride Diffusion: Developed a fully coupled nonlinear model (finite difference) for the coupled diffusion of chloride and carbonation in concrete. Applied this model to subsequently determine the extent of corrosion and cracking in the concrete.
- Nonlinear finite element simulation of reinforced concrete: This is an extension of my work in dams. Having the appropriate computational tools (MERLIN), I have performed the nonlinear analysis of a portion of a nuclear reactor containment vessel, and performed a number of simulations (with Prof. Al-Mahaidi and Spacone) for the fracturing of FRP.
Computer ProgramsDeveloped, supervised development of the following computer programs:
