Advanced Optical Methods and Structural Optimization

Contact person

Luciano Lamberti - Associate Professor

Competencies and research activities

- Interferometric techniques  (speckle, moiré and holography) are applied to stress/strain analysis  of electronic components, biological specimens and industrial components, reconstruction of 3-D shape of objects, evaluation of thermal distortions and residual stresses, identification of constitutive behavior of materials with high nonlinearities (e.g. biological membranes). 
- Nanosciences: nanolography, roughness measurement with nonconventional illumination (e.g. evanescent fields), measurement of strains of crystalline arrays (at dislocation level).
- Gradient-based (SLP, SQP and modified feasible directions) and metaheuristic optimization algorithms (simulated annealing, harmony search, big bang-big crunch, firefly algorithm, heat transfer search) have been developed for sizing and layout optimization of large-scale skeletal structures, preliminary design of liquid hydrogen tank,  and hybrid methodologies for mechanical characterization of materials (composites, biotissues, cells).
