Effect of MTAD, Qmix 2 in 1 and Sodium Hypochlorite on Modulus of Elasticity and Flexural Strength of Dentin Aim The aim of the present study was to evaluate and compare the effect of MTAD, Qmix 2 in 1 and sodium hypochlorite on flexural strength and elastic modulus of dentin. Materials an...
The proposed system uses a USB microscope that captures images at a rate of five frames per second. The stored data are correlated with the applied loads, and a stress-strain curve is generated to determine the concrete compressive modulus of elasticity. Two different concretes were produced and...
E 0 is the modulus of longitudinal elasticity, Fll(t) is the rate of longitudinal relaxation, ~(t)are the longitudinal stresses, and ~;tI(t) are the longitudinal strains. The moduli of elasticity E 0 and G O are sometimes called momentary, which emphasizes the fact that they can be det...
Individual strain gages were modeled using elements (Truss2D), which allowed easy retrieval of strains. After that the elements of the strain gage model were applied to the finite elements grid model of the plate (Solid8). Modulus of elasticity of the elements is E=1.10-6 MPa. We used st...
