APPLICATIONS OF PHOTOMECHANICS IN TISSUE BIOMECHANICS
Amir Zadpoor
Abstract: Advanced imaging techniques are often combined with computational and analytical models to characterize the biomechanical behavior of biological tissue and biomaterials. The biological tissues are characterized at different spatial and time scales and could vary from skeletal tissues such as bone and cartilage to soft tissues such as liver and brain. This talk will review the state of the art in application of photomechanics to characterization of the biomechanical behavior of various types of biological tissue and biomaterials with an emphasis on skeletal tissues. The multi-physics nature of the problem, i.e. coupling of the mechanical behavior with chemical and electrical behaviors, will be also addressed. The included imaging techniques vary from full field strain measurement techniques such as digital image correlation and digital volume correlation that are often used for characterization of the mechanical behavior of biomedical materials to multi-physics techniques based on (nano/micro-) computed tomography that are used for simultaneous characterization of the chemical, electrical, and mechanical behavior of biological tissues.
