... fracture mechanics concepts, the reinforcing effects of a BFRP bar on the fracture properties of BFRP bar–reinforced Eco-HDCC specimens were studied. First, cracking load, crack mouth opening displacement (CMOD), and deflection of specimens were monitored, and BFRP bar diameter and cover thickness were...

... and deflection of steel-plastic geogrid and its control of surrounding rock deformations were studied and analyzed using laboratory and engineering field tests. We have contrasted the tensile strength of steel-plastic geogrid to that of metal mesh. We have also contrasted the deflection deformation of the steel...

...Myoung Soo Won The present study investigates if improving the bearing capacity of foundations with reinforcement layers could reduce deflection of a pipe buried under reinforced sand. A series of model tests were conducted to examine the bearing capacity of foundations and deformation behavior...

... factors greatly overestimated failure times. A new method for predicting failure times using creep tests is presented here. Using the compression test machine, a constant load equal to a fraction of the ASTM D 642 compression strength was placed on a test box and the deflection was recorded over a 12 h...

... was initiated to determine the sample size (% mileage) at the network level as well as the test intervals and frequency that can be used as guides for network-level deflection testing and structural evaluation of pavements. Falling-weight deflectometer (FWD) data, collected on 571 km (357 miles) of non...

... of the modulus, will best fit the experimental displacements. An equation is proposed for the displacement with terms including beam deflection and a quantity proportional to load travel, and a method to calculate the modulus from the experimental displacements is given. Finally, the experimental system...

...MS Mamlouk At present, there is no direct solution that provides the pavement in-situ layer moduli from deflection measurements. Current methods evaluate the pavement layer moduli from deflection measurements using either empirical approaches or layered elastic computer programs with iterative...

...D Hellmann; G Rohwerder; K-H Schwalbe A test setup was developed for the measurement of the deflection of single-edge notched bend (SENB) specimens. It avoids the influence of the indentations resulting from the roller pins during the measurement of the deflection. Compliance calibration bend tests...

...). The toughness, the square root of the fracture initiation energy, and the specimen deflection at fracture initiation follow similar trends under identical conditions in each type of testing. Thus fracture initiation energy and the specimen deflection in Charpy testing can be measures of toughness. These three...

...SG Paolinelis; SA Paipetis; PS Theocaris An analytical investigation of three-point bending at large deflections was carried out with materials exhibiting different moduli of elasticity in tension and in compression. It was found that the solutions developed by the authors elsewhere for equal...

...-amplitude-of-deflection of the specimen proposed in this paper accommodates up to 16 specimens simultaneously, thereby substantially reducing the time required for the test. Constant-amplitude-of-deflection of the specimen is effected by rotation of its builtin end. Experimental data are presented that show...

...PS Theocaris; SA Paipetis; S Paolinelis A complete investigation of three-point bending at large deflections was attempted with the view of applying it as a test method for the determination of the effective modulus of elasticity of materials. A general solution of the problem was attempted...

... property changes. The TMA method involves measurement of deflections in specimens loaded in three-point flexure while the temperature is increased at a constant rate. The technique is similar to that described in ASTM D 648 for determining temperatures at which arbitrary amounts of deflection have been...
