stress relaxation การใช้

• Stress relaxation describes how polymers relieve stress under constant strain.
• Creep and stress relaxation measures the Tensile geometry is the most common for creep measurements.
• The piece then heat-soaks until its temperature is even throughout and the stress relaxation is adequate.
• Although the Maxwell model is good at predicting stress relaxation, it is fairly poor at predicting creep.
• The evening workout stresses relaxation, teaching self-massage techniques to relieve tension in the back, shoulders and neck.
• A complementary property is stress relaxation, where a strain is applied and the corresponding stress change is measured.
• On the other hand, the Voigt model is good at predicting creep but rather poor at predicting stress relaxation ( see Viscoelasticity ).
• Stress relaxation is available using any standard universal test instruments, since their mode of operation is application of strain, while the stress is measured.
• Other therapies, which were less helpful than prayer but more helpful than having no such care, included guided imagery, stress relaxation, and healing touch.
• Many mechanical properties of polymers have an Arrhenius type relationship with respect to time and temperature ( for example, creep, stress relaxation, and tensile properties ).
• The advantages of strain control include a better short time response for materials of low viscosity and experiments of stress relaxation are done with relative ease.
• In stress confinement, which occurs when the laser pulsewidth is much shorter than the stress relaxation time, Eq . ( 2 ) can be further derived as
• He authored numerous scientific papers in his research specialties which centered upon stress relaxation and internal friction, and served as editor of a Polish scientific journal and a visiting professor abroad.
• A strain energy density function is used to define a hyperelastic material by postulating that the strain ( elongation ) components, thus disregarding the deformation history, heat dissipation, stress relaxation etc.
• It accounts for variation in load, strength and stress leading to failure at high level of detail, possible with use of modern finite element method ( FEM ) software programs that may handle complex geometries and mechanisms like creep, stress relaxation, fatigue and probabilistic design ( Monte Carlo simulations / DOE ).
