Plate Perforation

This paper presents the results of an experimental and numerical study of the perforation of Armox 500T armoured steel. The plate perforation was performed with a pneumatic gun using three types of penetrators. Sharp, spherical and blunt penetrators were used. The use of different geometries of penetrators causes the process of perforation and destruction of plates in a different state of stress and strain, which leads to the appearance of three basic modes of failure. Numerical analyses of the perforation process have been carried out using the Ls-Dyna computational code with an advanced constitutive model of the material and the integrated failure model. The obtained experimental and numerical results were analysed and compared. The failure shape, the level of plastic deformation and the parameters of stress and strain state were analysed.

Actual Evaluation

The following is an investigation to determine completely the state of stress and strain in spinning paraboloid dishes both whole and holed at the center. The material of the dish is homogeneous and its thickness is constant. The results comprise expressions for the radial, hoop, and shear stresses, the bonding moments, and deformation induced by the spinning of the dish in terms of the angular distance from the center of the dish. Tables at the end of the paper make the actual evaluation of these stresses, moments, and deformations a matter of simple arithmetic.

Holistic Understanding

Tissue mechanics is one of the key courses of the Biomechanics subtrack of the undergraduate curriculum. The aims of the course include: 1) To understand the concepts of stress, strain, viscoelasticity and how these concepts apply to musculoskeletal tissues. 2) The ability to infer the state of stress and strain at a given point in a biological structure under torsional, axial, bending and other types of loads. 3) To understand the anatomy of musculoskeletal tissues. Accomplishment of these aims requires a holistic understanding of statics, strength of materials and microanatomy of connective tissues. Conveying this wide range of topics in one class is a major challenge and most textbooks on this subject lack depth either in engineering or in physiology. The purpose of this abstract is to describe the benefits of the integration of theory with experimental practice for bridging the difficult topics of statics, strength of materials and tissue anatomy within the framework of undergraduate biomedical engineering curriculum.

Based on application the physical constraint equations of state of stress and strain of the metal for the isotropic medium, we get expressions for components of stress tensor. The new theoretical method for calculation of contact pressures and rolling force during rolling of double-T section in a universal beam groove was developed. Reliability of the method is confirmed by the results of experimental verification for conditions of rolling of H-beam No 35B1, 40K2 and 45B2 from steel 15CrSiNiCu on the universal beam mill of "NTMK". The average calculation error is 6.4%. The new method is recommended for calculation pass design and technological modes of H-beam rolling on rail-beam and section mills, equipped with universal stands.
