Time temperature superposition
Hi, I am trying to evaluate viscoelastic properties of a polymer through dynamic mechanical analysis. I am using time temperature superposition principle to evaluate properties at extended frequency. I am wondering if there is any formula that relates temperature with time (or frequency) which...- patrickmech

Modal analysis with dampers
Hi, I am trying to do experimental modal analysis on a structure with tuned mass dampers (TMD) mounted discreetly on it. When compared to testing an undamped (without TMDs) structure, what are the issues / precautions that need to be considered while testing, curve fitting? Suggestions on how...- patrickmech
