Residual Stresses in Layered Manufacturing [PDF]

open access: yes, 1999
Layered Manufacturing processes accumulate residual stresses during materialbuildup. These stresses may cause part warping and layer delamination. This paper presents work done on investigating residual stress accumulation andp(i,rt distortion of ...

Advanced Mapping of Optically-Blind and Optically-Active Nitrogen Chemical Impurities in Natural Diamonds

open access: yesChemosensors, 2022
Natural diamonds with a rich variety of optically blind and optically active nitrogen impurity centers were explored at a nano/microscale on the surface and in bulk by a number of advanced chemical and structural analytical tools in order to achieve a ...

Interplay of internal stresses, electric stresses and surface diffusion in polymer films

open access: yes, 2011
We investigate two destabilization mechanisms for elastic polymer films and put them into a general framework: first, instabilities due to in-plane stress and second due to an externally applied electric field normal to the film's free surface.

Quasistaticity of the process of dynamic strain of soils

open access: yesИнженерно-строительный журнал, 2019
Mechanical characteristics of soil under static and dynamic strains are determined experimentally. Their accuracy and reliability depends on quasi-static nature of strain process in soil.

Contributions to the Dynamic Regime Behavior of a Bionic Leg Prosthesis

open access: yesBiomimetics, 2023
The purpose of prosthetic devices is to reproduce the angular-torque profile of a healthy human during locomotion. A lightweight and energy-efficient joint is capable of decreasing the peak actuator power and/or power consumption per gait cycle, while ...
