Impact Toughness of Mower Blades
SAE Technical Paper Series, 1994<div class="htmlview paragraph">The purpose of this work is to improve the safety and durability of agricultural and off highway rotary cutter blades. Field experience has resulted in specifying low blade hardness to prevent catastrophic impact failure and the obvious safety concerns.

Impact fracture toughness tests on polymers
Polymer Engineering & Science, 1990AbstractA series of impact tests are described in which the plane strain fracture toughness, Kc1, of five different polymers is measured using a three point bend specimen at striker speeds up to 5m/s. At low speeds Kc1 is determined using the maximum load and a static analysis, but at speeds greater than 1 m/s the dynamic effects render the load signal

Fracture and Impact Toughness of Syntactic Foam
Journal of Cellular Plastics, 2004In this study we assessed the fracture toughness, KIc, and the impact resistance of syntactic foam reinforced with glass microspheres of different densities and polymer binder as a function of microstructures. The results showed that both KIc and the linear elastic energy release rate, GIc, increased with increasing volume fraction of glass ...

Impact modifier boosts toughness of films
Plastics, Additives and Compounding, 2008Films are among the most important products to be made of polyolefins. Since they are primarily mass-produced, even slight reductions in the film thickness have the potential to lead to considerable savings. Robert Huber and Jorg Auffermann of BASF explain how Styroflex® 2G 66 SBS block copolymer can be used to increase the puncture resistance and the ...

Heat Treatment and Impact Toughness of the F55-Grade Steel
Materials Performance and Characterization, 2020ABSTRACT Low-temperature impact tests are commonly performed to test the quality of industrial forgings in Duplex Stainless Steels (DSS). The F55 grade is a highly alloyed Super DSS characterized by excellent low-temperature toughness in the solution annealed condition.

Quantile Regression Model for Impact Toughness Estimation
2010The purpose of this study was to develop a product design model for estimating the impact toughness of low-alloy steel plates. The rejection probability in a Charpy-V test (CVT) is predicted with process variables and chemical composition. The proposed method is suitable for the whole production line of a steel plate mill, including all grades of steel

Effect of plastic deformation on impact toughness
Strength of Materials, 19841. With a completely ductile fracture, 10% prior cold tensile and compressive deformation have the same effect on the impact toughnessai of the investigated tube steels, reducing it by about 30%. In the region of the ductile-brittle transition, impact toughness may be reduced by 50–60% as a result of preliminary plastic strain, depending on the ...

Impact Fracture of a Tough Ductile Steel
1990The impact fracture of a tough ductile material is examined by comparing the results of static and dynamic viscoplastic finite element computations with experimental observations of the crack tip opening displacement (CTOD) during static and dynamic (impact) fracture.

Notch Impact and Fracture Toughness Testing
1992When an external stress is applied to a material, the material will be deformed, or strained. If the magnitude of the stress is increased, the material will eventually fail by fracturing. Not all materials fail in the same manner, and the type of fracture that occurs may be either brittle or ductile.

Impact fracture toughness of polyvinyl chloride
Colloid and Polymer Science, 1974The strain rate sensitivity of a rigid polyvinyl chloride has been investigated over a range of temperatures (−197 to 80 °C) and Linear Elastic Fracture Mechanics has been applied to evaluate the results. Tests onCharpy type1) specimens provided with sharp notches were carried out at two widely different strain rates; in “static” conditions and in a ...
