Measurement of the dynamic modulus of elasticity of wood panels
      
This study investigated the dynamic modulus of elasticity (DMOE) of wood panels of Fraxinus mandshurica, Pinus koraiensis, and Juglans mandshurica using the natural frequency measurement system of fast Fourier transform (FFT).

The softening point and Young's modulus of polymethylmethacrylate at low temperature with various contents of dibutyl phthalate have been measured by using a consistometer and a dilatometer respectively. The relationship between the molar con- centration of dibutyl phthalate, N, and the softening point, T, can be expressed by the equation T=112-947N. An explanation for the difference between the coefficient 947 and the value 228-232, previously obtained by Zhurkov, is suggested. The addition of 1% or...

The softening point and Young's modulus of polymethylmethacrylate at low temperature with various contents of dibutyl phthalate have been measured by using a consistometer and a dilatometer respectively. The relationship between the molar con- centration of dibutyl phthalate, N, and the softening point, T, can be expressed by the equation T=112-947N. An explanation for the difference between the coefficient 947 and the value 228-232, previously obtained by Zhurkov, is suggested. The addition of 1% or more dibutyl phthalate substantially improves the low temper- ature impact strength of polymethylmethacrylate, but it shows no appreciable change in Young's modulus at room temperature with 1-5% dilbuytl phthalate.

An investigation of the rheological relationships between shear stress shear rate apparent bulk viscosity temperature was carried out by examining the viscous flow of slightly milled native Hevea rubber (i) The Eisenschitz's equation for non-Newtonian flow has been verified by the experiments on the dependence of shear rate on shear stress. By this equation, the apparent viscosity can be referred to the Newtonian viscosity η_0 (at σ=0). The parameter (G_i=3.30×10~5 dynes/cm~2), interpreted as an internal modulus of rigidity, was found to be practically independent of temperature in the range of 50-90℃, thus agreeing with the results by treating Saunder and Treloar's data. (ii) For the shear rate dependence of apparent viscosity, when the number of Khun segments per unit volume was taken into account for the calculation of retardation time τ_1=2.84η_0 [J_e]_∞, the Debye-Bueche's equation was found to be able to fit into our data at moderate low shear rates. The values of steady-state elastic compliance [J_e]_∞ were determined by elastic-recovery experiments. Furthermore, the internal shear modulus Gi could be thus calculated by combining the Eisenschitz's equation with the Debye-Bueche's one. (iii) From the experiments on the temperature dependence of viscous flow under various stresses, the apparent activation energy ΔE_η was found to be 12.7 kcal/mole; and therefrom, by estimation, the unit of flow-the Eyring segment would be 30 carbon atoms long. All determinations of the flow rate under constant stress were carried out in a Hppler parallel-plate plastometer, used as a viscoelasticity-rheometer according to the theory developed by Dienes.

In this Paper,the important problems of temperature stresses in arch dams are analyzed. Firstly,we consider the transient elastic three dimensional temperature stresses.It is pro- posed to cut the dam into horizontal and vertical systems,compute the stresses and dis- placements arisen therein by the nonlinear temperature distribution on the assumption of Plane section of Bernoulli-Navier,then adjust the displacements of the horizontal and ve- rtical systems by the so called trial load method.Some tables are prepared to simplify the calculation.A simple method is suggested to calculate stresses in thick archs.The method of equivalent hydraustatical pressure for temperature variations in arch dams is discussed. The defects of this method are pointed out. Secondly,the influence of creep of concrete is considered.For mature concrete the creep C(t,τ)may be expressed by the following formula: C(t,τ)=C_[1-e-r(t-τ)](49) Where Co and r are constants determined by tests,τ is the time at which the load is applied,and t is the time considered.Then for the sinusoidal temperature stresses,σ= F(x,y,z)sin t,the coefficient k of stress relaxation may be computed by k=sinθ-E_C_r·(g sinθ-ωcosθ)/g~2+ω~2(59) θ=tan~(-1)[(g~2+ω~2)/(E_C_rω)-g/ω](58) Where k=(max.elastic temp.stress)/(max.Visco-elastic temp.stress), E_0=Young's modulus of concrete,θ=time lag of max.str,g=r(1+E_0C_0).As shown in the second example,for concrete of portlant cement,k=0.417 for annual temperature variations,k=0.993 for 15 days Variations,k=1.00 for daily Variations,the stress-time curves are shown in Fig.10.Cofficient k is independent of x,y,z. Thirdly,the problem of subcooling is considered.The stresses caused by subcooling at the time of grouting contraction joints are also reduced by creep of concrete at later time. The final coefficient k of stress relaxation may be computed by k=1/(1+E_0C_0)(65) As shown in the third example,k=0.357 for concrete of portlant cement.
