The Effect of Pre-strain and Strain Path Changes on Ductile Fracture
… The mechanical behavior of materials undergoing strain path changes can be very different from those deformed in a given direction to fracture. The work presented here employed laser drilled model materials to better understand the effect of pre-strains and strain path changes on void growth and …

Finite strain behavior of polyurea for a wide range of strain rates
… as its high toughness-to-density ratio and high strain rate-sensitivity, so its application is recently extended to structural purpose to form sandwich-type or multi-layered plates. Those structures can be used for retrofitting of military vehicles and historic buildings, absorbing energy during …

Dual-Use Strain Sensors for Simultaneous Strain Measurement and Acoustic Source Location
The use of metal strain gauges and ultrasonic transducers have long been studied in the field of Nondestructive Evaluation (NDE) as a part of structural health monitoring (SHM). Strain gauges use electrical resistance to monitor strains during the loading of a component. Ultrasonic transducers are …

High Deviatoric Strain Engineering/
… or irreversibly by imposing elastic or inelastic strain, leading to change of properties. This defines the concept of strain engineering, which includes both elastic strain engineering (ESE) and inelastic strain engineering (ISE). In this thesis, we study ESE and ISE by deviatoric (nonhydrostatic) …

Strain Rate and Temperature Controls on Strain Heterogeneity: Its Significance for Deformational Concepts
… the relative influence of temperature and strain rate upon the promotion of strain homogeneity. The experimental results are used to help evaluate the important analytical techniques of shape factor analysis and the use of strain heterogeneity to establish a path of progressive deformation.

Mechanisms of Prion Strain Interference
… PrPSc are hypothesized to encode different prion strains, and the type of prion strain affects the disease incubation period, clinical signs, and neuropathology. Prions can exist as a mixture of strains in a host, and one implication of prion mixtures is that prion strains can interfere with one …

Longitudinal misalignment based strain sensor
A practical fiber optic strain sensor has been developed to measure strains in the range of 0.0 to 2.0 percent strain with a resolution ranging between 10 and 100 microstrain depending on sensor design choices. This intensity based sensor measures strain by monitoring strain induced longitudinal …
