This paper reports a series of strain-controlled low-cycle fatigue experiments for high-strength steel S550 under different strain ratios at the room temperature. Based on the experimental results, this paper calibrates the cyclic plasticity parameters and presents the cyclic stress-strain curve, the...
Hence, accelerated testing of chloride penetration appears to be a more valuable way to test the permeability than testing the electrical conductivity. 展开 关键词: Cement content Chlorides High strength concrete Lightweight concrete Permeability Water ...
Results of 25°C penetration, softening point, 5°C ductility, dynamic shear rheometer (DSR), blending beam rheometer (BBR) tests and Burger's model calculation indicate that OMMT and TPU can dramatically improve high and low temperature properties, temperature susceptibility and elastic behavior of...
5. MOQ: 2000 kgs 6. Special treatment: High tensile strength, anti-UV treated 7. Application:widely used as housewrap, underlayment for wood buiding as the roofing, wall protection, to anti dust, keep the house warm, and it is breathable, the water vapour can pas...
5), exhibit adhesion strengths of 1.8, 27, and 122 kPa, respectively (Fig. 2j). It is the low viscosity of the material and the low adhesion strengths of the interface that greatly reduce the rapid response and relaxation time. Second, the graded structure—microdomes with finer ...
Here, we present a design strategy that enables laser AM of Cu parts with high density and high performance through the addition of minute amounts of lanthanum hexaboride (LaB6) nanoparticles. Our LaB6-doped Cu exhibits a yield strength of 347 ± 2 MPa (which is 3.7 times higher ...

He derived a more complex formula for the depth of penetration involving a drag coefficient (related to the strength of the resisting medium) and a critical impact velocity. However, Gaite’s assessment of Gamow was that: “Gamow’s formula is, in fact, a sensible and quick rule for ...
