Focused on the mechanics and thermodynamics of material
response, Negahban and his group work on a broad range of problems in continuum
mechanics and thermodynamics, numerical simulation and materials
characterization. These include:
·
Continuum mechanics and
thermodynamics
o
Material
symmetry and its evolution in material response models
o
Thermodynamics
of solids
o
Nonlinear
elastic, plastic, and viscoelastic response
o
Internal
state variable models
o
Thermodynamics
of glassy polymer response
o
Phase
transformation in polymers
o
Failure
in metals
o
Mechanical
testing
o
Digital
Image Correlation (DIC)
o
Dynamic

o
Fourier
Transform Infrared (FTIR) spectroscopy
o
Differential
Scanning Calorimetry (DSC)
o
Finite

material grading
·
Manufacturing and
process simulation
o
3D
