elasticity test
1.In the real life analysis on CEV model (Constant Elasticity of Variance Model),its unit root test is long been ignored or at most Dickey-Fuller Test is accepted as a valid test.
2.GROUND TEST RESEARCH ON SERVO-ELASTICITY OF BW-1 VARIABLE STABILITY AIRCRAFT
3.As a common interest rate model,CEV model (Constant Elasticity of Variance Model) has been widely used in the real life analysis. However,its unit root test has long been ignored or at most Dickey?Fuller Test is accepted as a valid test.
4.At last, the test setting was theoretically analyzed by mechanics of elasticity, and the theoretical stress and actual stress of ring specimens were calculated. In combination with the test of tensile strength, evaluation on cracking potential and stress relaxation of ring specimens was made.
5.This paper presents on approximate comforming element, namely, ths quasi-comforming element in terms of string net function, derived from weak formulation of comtinuity equation in elasticity, Itverifies that the quasi-com foring element has passed the patch test and satisfied the rigid body disp- lacement condition, and proposed a method to construct the hyperbolic shell element.
6.Firmness changes in harvested "Fuji" apples were measured by nondestructive acoustic impulse response test,destructive texture analysis and background color measurement. The changes of nondestructive measured stiffness coefficient (S),maximum puncture force (F_(max)),modulus of elasticity (E) and hue angle (H°) were monitored under different storage conditions.
7.Filling flexibilizer, such as epoxy terminal block, polyurethane ether structure, thiokol and liquid CTBN to the system of expoxy-Mannich amide, through the test on shear strength, bounding elasticity modulus and break strength of cured products, the different fuction could be found using different flexibilizers.
