“…Whether the operating mechanism of university education management can adapt to the internal and external environment and maintain efficient operation is related to its regulatory role. With the implementation of comprehensive deepening reform, optimizing the management operation mechanism, enhancing the vitality of running a school, making it adapt to the pace of comprehensive reform, and promoting the healthy and rapid development of university education are the new topics currently facing [5,6].…”

The reform and development of university education management are operating according to their own laws with the changes of the internal environment of education and the social external environment such as politics, economy, science and technology, and culture. As a branch of the mechanism of university education management, the operation mechanism of university education management supports the reform and development of university education management. This article studies the construction of a university education management model based on an intelligent programming analysis method. The research shows that the average score of the control class before the experiment is 63.7748 and the average score of the experimental class is 63.8954. It can be seen that the average score difference between the two classes is only 0.1206. Understand the performance changes of various dynamic forces by gradually contacting complex structures. Through building + intelligent programming, we can preliminarily understand programming and increase children’s interest in programming; strengthen programming ability; learn various complex structures; and lay a good foundation for later intelligent programming. This article studies the intelligent programming education of university education management and solves the problems existing in University Programming Education by formulating relevant policies, changing teaching methods and using after-school time, so as to optimize the teaching effect.

“…At the same time, the plate’s weight was more than the other tested plates. Hence, nanocomposites can be incorporated [ 37 , 38 ]. Sophisticated non-local damage models based on the phase-field approach to fracture can be employed to improve the numerical prediction, see [ 39 , 40 , 41 ].…”

Design and Evaluation of Hybrid Composite Plates for Ballistic Protection: Experimental and Numerical Investigations

In this paper, hybrid composite plates for ballistic protection were investigated experimentally and numerically, with a target to reduce the weight of currently used body armor inserts and, at the same time, satisfy the requirements of the National Institute of Justice’s (NIJ) ballistic protection standards. The current study has three phases to improve the ballistic plate’s energy absorption capability. The first phase is devoted to studying the effect of the material types, including three different fibers: carbon fiber, date palm fiber, and Kevlar fiber. The second phase is dedicated to studying the effect of hybridization within layers. The two previous phases’ results were analyzed to optimize the material based on the hybrid composite ballistic plate’s maximum energy absorption capability. The commercial finite element software package LS-DYNA was employed for numerical modeling and simulation. The hybrid composite ballistic plate could absorb more impact energy than the non-hybrid Kevlar plate with the same area density from the numerical simulation results. This study provides lighter-weight ballistic inserts with a high protection level, making movement easier for the wearer. The numerical results were verified by comparing results of a plate made of 40 layers of Kevlar with an actual ballistic test. The results indicated that the simulation results were conservative compared to the ballistic test.

Singh et al (2017b) examined the effect of different factors (initial stress, irregularity depth, irregularity factor and magneto-elastic coupling parameter) on the dynamic response due to a normal moving load with constant velocity on the free surface of an irregular magneto-elastic transversely isotropic half-space under the state of hydrostatic initial stress.…”

Response of moving load over a surface is an intriguing problem of mechanics to determine the stability and strength of a structure. Owing to this the present theoretical framework is devoted to find the stresses and electrical displacements of an irregular visco-porous piezoelectric half-space originated due to a uniformly moving line load. Expressions for normal stress, shear stress and electrical displacements have been derived in closed form. Effect of irregularity depth, irregularity factors and frictional coefficient on the stresses and electrical displacements are delineated graphically. Numerical demonstration of procured results is interpreted by means of graphs for two different materials, namely PZT-5A and PZT-7. A comparative study emphasising various irregularity (parabolic, rectangular and no irregularity) is among the salient features of the study.
