Riccioli, F. (author), Huijer, A.J. (author), Grasso, Nicola (author), Rizzo, Cesare M. (author), Pahlavan, Lotfollah (author)Measurement of transient pressure distribution on maritime structures is important for the assessment of the hydrodynamic loads applied. The commonly used pressure sensors are mostly bulky, need to be bolted to the structure, and/or only provide point-wise measurements. In this paper, an elastic matrix layer with a network of embedded...journal article 2023

Unnikrishnan, Gokul Krishna (author), Sharma, S. (author), Pathak, Himanshu (author), Chauhan, Vishal Singh (author), Jain, Satish Chandra (author)To accurately analyze the fracture behavior of piezoceramics at small length scales, flexoelectricity must be considered along with piezoelectricity. Due to its dependence on size, flexoelectricity predominates at the micro- and nano-length scales. Additionally, crack tips having the largest strain gradient state cause large flexoelectricity...journal article 2023
