buckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Measurement of Thermal Expansion Coefficient Using Strain Gages
w w w. v i s h a y m g . c o m VMR-TC0513-0501 The thermal expansion coefficient is a very basic physical property which can be of considerable importance in mechanical and structural design applications of a material. Although there are many published tabulations of expansion coefficients for the common metals and standard alloys, the need occasionally arises to measure this propertay for a sp...
متن کاملThermal Expansion and Magnetostriction Measurements at Cryogenic Temperature Using the Strain Gauge Method
Thermal expansion and magnetostriction, the strain responses of a material to temperature and a magnetic field, especially properties at low temperature, are extremely useful to study electronic and phononic properties, phase transitions, quantum criticality, and other interesting phenomena in cryogenic engineering and materials science. However, traditional dilatometers cannot provide magnetic...
متن کاملNegative thermal expansion and anomalies of heat capacity of LuB50 at low temperatures.
Heat capacity and thermal expansion of LuB50 boride were experimentally studied in the 2-300 K temperature range. The data reveal an anomalous contribution to the heat capacity at low temperatures. The value of this contribution is proportional to the first degree of temperature. It was identified that this anomaly in heat capacity is caused by the effect of disorder in the LuB50 crystalline st...

For technical support, contact [email protected] www.vishaymg.com 19 Revision 15-Aug-07 I. Residual Stresses and Their Measurement Residual (locked-in) stresses in a structural material or component are those stresses that exist in the object without (and usually prior to) the application of any service or other external loads. Manufacturing processes are the most common causes of r...
