Research

• A new micromechanics-based and three-dimensional framework for the nonlinear viscoelastic analysis of laminated and pultruded composites. The constitutive models can predict the effective and overall viscoelastic response of the composites, given the in-situ fiber and matrix properties.
• Nonlinear multi-scale modeling of thick-section laminated and sandwich composite materials and structures. A new nonlinear sublaminate method is introduced to generate the through-thickness 3D effective viscoelastic response of a repeating stacking sequence in the layered laminate.
• Short term creep tests on off-axis FRP laminated coupons under different load levels subject to various temperature, moisture, and aging conditions. Create master curve in order to characterize long-term (over 20 years) nonlinear creep responses using time-temperature superposition principle (TTSP.
• Creep buckling and collapse analyses of FRP composite structures. The compressive loading ratio, along with the residual stiffness of the structure after buckling, can affect the creep behavior and the magnitude of the critical time for initiation of unstable response
• Recursive-iterative numerical integration algorithm for time-dependent responses in polymeric matrix and stress-correction algorithm for nonlinear multi-scale response.
• Time-dependent damage modeling on FRP composite materials.
• Modeling creep response on nanoindentation tests.
