Evaluation of the Types and Mechanisms of Fracture of Composite Materials According to Energy Criteriadoi:10.1007/978-3-031-11291-1_4In recent years, the use of CM as a structural component in many branches of industry, including aerospace, rocket and space, chemical, automotive, for the ...
Acoustic emission (AE) signals obtained from static loading tests on different structural materials were processed by wavelet transform (WT) technique. Wavelet analysis is used to determine new relevant descriptors in order to improve the characterization and the identification of the fracture type: ...
The recent developments of cryogenic austenitic steels are reviewed. The cryogenic fracture model and its mechanism in high manganese or high nitrogen austenitic steels are discussed. It is pointed out that stacking fault energy, critical resolved shear stress for phase transformation, the cleavage stren...
The general purpose of our study is the determination of the energy parameter J when dealing with fracture of rubber-like materials. The energy parameter J is expressed in a multiplicative form in which a calibration factor is introduced in order to take into account the finite dimensions of the...
Thermoplastic Additives –They are used to increase the fracture toughness of epoxy resins. Only relatively low MW TPs can be dissolved in epoxy resins. Commonly used thermoplastics are: phenoxy, polyether block amides, PVB, polysulfone, polyethersulfone, polyimide, polyetherimide, nylon. As compared...
Types of Materials材料的类型 Materials may be grouped in several ways. Scientists often classify materials by their state: solid, liquid, or gas. They also separate them into organic (once living) and inorganic (never living) materials.
