We prove the existence and uniqueness of solution to a classical creep damage problem. We formulate a sufficient condition for the problem to have a unique smooth solution, locally in time. This condition is stated in terms of smoothness of given data, such as solid geometry, boundary conditions, applied loads, and initial conditions. Counterexamples with an arbitrary small lifetime of a struct...

Pathophysiological conditions of the lung may shift the balance of forces so as to chronically alter the amount of strain imposed on the airways. This chronic strain could result in changes in the structure and/or function of the airways that affect its physiological properties. We evaluated the effects of imposing physiological levels of chronic mechanical strain on the passive and active phys...

We present a prediction for the formation of surface defects in a thin amorphous silica layer during relaxation of externally imposed stresses and strains, based on extensive ab initio molecular dynamics calculations. Our calculations show that the application of a biaxial compressive stress leads to the creation of edge-sharing tetrahedron and/or silanone defects at the silica surface, which t...

We present a Finite Element (FE) approach to model the conductivity and strain-sensing capabilities of Carbon Nanotube (CNT) reinforced polymer composites. A periodic Representative Volume Element (RVE) is constructed based on measurable statistical descriptors of the microstructure, and its response is simulated by concurrent electrical and mechanical FE analyses; the scatter of the prediction...

Abstract The individual effects of strain rate and temperature on the hardening a quenched partitioned steel have been examined. During quasistatic tests, resistive heating was used to simulate deformation-induced that occurs during high-strain-rate deformation, while martensitic transformation tracked by combination x-ray electron backscatter diffraction. Unique work rates under various therma...

Mechano-Optical Sensors In article number 2104702, Osamu Tsutsumi and co-workers report a multilayered concept for tuning the recovery response of cholesteric liquid crystal elastomers, enabling flexible, stretchable, sensitive mechano-optical sensor with on-demand spatiotemporal resolution. The mechanical strain imposed on can be visualized quantified using commercially available camera as wel...
