An Investigation on the Nose Mass Abrasion of Projectile Fei Qian1, Haijun Wu*1,a, Fenglei Huang1, Yinan Wang1 1State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing, 100081, China *awuhjbit@hotmail.com (corresponding author) Key words: Mass abrasion, High-speed penetration, Kinetic energy penetrator, Concrete target Abstract: Based on the dynamic spherical cavity expansion theory of concrete and the analysis of experimental data, a mass abrasion model of projectile considering the hardness of aggregates, the relative strength of target and projectile and the initial impact velocity is constructed in this paper.
However, relatively speaking, the sensitivity of strength of projectile to mass abrasion is higher, which indicates that the effect of projectile material on mass abrasion is more important than the hardness of aggregates. 1 Introduction The mass abrasion of projectile would occur obviously in high-speed penetration.
The hardness of aggregates and the strength of projectile is also the significant factor, but relatively speaking, the sensitivity of the strength of projectile to mass abrasion is higher, which illustrates that the effect of projectile material on mass abrasion is more important than the influence of the hardness of aggregates.

Sometimes even with the risk of a loss of stability that belongs to the category - brittle failures Introduction Based on the materials supplied by Statika Čížek, s.r.o. we selected a column of the hall for analysis.
The column selected for analysis and subsequent optimization (minimization of materials) has a variable rectangular cross-section.
Prices of individual materials were considered as follows.

Nondestructive Material Evaluation by Novel Electromagnetic Methods Gábor Vértesy, Antal Gasparics Research Institute for Technical Physics and Materials Science H-1525 Budapest, P.O.B. 49, Hungary Keywords: Eddy current testing, Magnetic flux leakage measurement, Magnetic field sensing Abstract.
The sensor can be effectively utilized for the detection of defects in conducting materials using eddy current testing measurements.
Electromagnetic way of nondestructive characterization of materials is one of the most promising methods and these methods are widely used in many different fields of the modern technology.
However, in many cases, it is still difficult to estimate the exact depth, position and shape of material inhomogeneities or the degradation of the materials, because the measured signal is frequently small and noisy.

Magnetic NW arrays based on various magnetic materials and alloys can be a basis for new types of memories, or used to improve already existing devices.
One of such interesting magnetic materials is a CoNi alloy, which can exhibit either a soft or a hard magnetic behavior, depending on the Co content in the alloy [7-10].
