The Role of Physical Education and Sports Teacher InPromoting Citizenship Values For Middle School Pupils

تكمن أهداف هذه الدراسة في إبراز الدور الذي يقدمه أستاذ التربية البدنية والرياضية في تعزيز بعض قيم المواطنة لتلاميذ الطور المتوسط، وذلك من خلال مجموعة من العمليات التي يقوم بها الأستاذ ويشترك فيها الأولياء بغرض ترسيخ مبادئ المواطنة لتلاميذ هذه المرحلة، ونظرا لصعوبة هذه المرحلة ألا وهي المراهقة، فإن الأستاذ هنا يحاول ويسعى بكل مجهوداته أن يغرس بعضاً من أبعاد المواطنة لدى تلاميذه، وقد استخدمنا في هذه الدراسة المنهج الوصفي لملائمته طبيعة الدراسة، وأما بالنسبة للعينة فأخذنا العينة العشوائية البسيطة، وأخذنا عينة تقدر بـ 64 فرد من مجتمع الدراسة، وتوصلت الدراسة إلى أن لأستاذ التربية البدنية دور كبير في غرس قيم المواطنة لدى التلاميذ.The aims of this study are to highlight the role offered by the teacher of physical education and sports in promoting some of the values of citizenship for middle school pupils, through a set of processes carried out by the teacher and the participation of the parents. in order to establish the principles of citizenship for the pupils of this stage, and due to the difficulty of this stage,  (adolescence), the teacher here tries his best  to inculcate  some of the dimensions of citizenship among his pupils, for this research  we have used  the descriptive method to suit the nature of the study, and as for the sample we took simple  random sample , estimated  of 64 members of the total number of the students , and the study found that the teacher of physical education played a major role in instilling the values of citizenship among students

Experimental and numerical analyses of a thin cylindrical shell model

The analysis of thin shell structures is generally based on theoretical principles. The experimental tests on this type of structure are important for understanding the effect of loading and the geometrical shapes on its mechanical behavior. In this paper, an experimental test of a cylindrical shell under the effect of concentrated static loads is presented. A comparative numerical study is carried out by using two finite elements: the first element called ACM_RSBE5, recently formulated, and the second one, S4R, of ABAQUS code are used for the study of thin shells. The experimental results are compared with those obtained numerically. The results of both elements, ACM-RSBE5 and S4R, are in agreement with those obtained experimentally. The efficiency and the importance of the approach of the flat shell element for thin shell structures are confirmed

Efficiency of the Strain Based Approach Formulation for Plate Bending Analysis

In recent years many finite elements have been developed for plate bending analysis. The formulated elements are based on the strain based approach. This approach leads to the representation of the displacements by higher order polynomial terms without the need for the introduction of additional internal and unnecessary degrees of freedom. Good convergence can also be obtained when the results are compared with those obtained from the corresponding displacement based elements, having the same total number of degrees of freedom. Furthermore, the plate bending elements are free from any shear locking since they converge to the Kirchhoff solution for thin plates contrarily for the corresponding displacement based elements. In this paper the efficiency of the strain based approach compared to well known displacement formulation is presented. The results obtained by a new formulated plate bending element based on the strain approach and Kirchhoff theory are compared with some others elements. The good convergence of the new formulated element is confirmed

A Comparative Study between Displacement and Strain Based Formulated Finite Elements Applied to the Analysis of Thin Shell Structures

The analysis and design of thin shell structures is a topic of interest in a variety of engineering applications. In structural mechanics problems the analyst seeks to determine the distribution of stresses throughout the structure to be designed. It is also necessary to calculate the displacements of certain points of the structure to ensure that specified allowable values are not exceeded. In this paper a comparative study between displacement and strain based finite elements applied to the analysis of some thin shell structures is presented. The results obtained from some examples show the efficiency and the performance of the strain based approach compared to the well known displacement formulation

A new strain-based finite element for plane elasticity problems

Purpose The purpose of this paper is to develop a new quadrilateral strain-based element. The element has five nodes, four at the corners as well as an internal node. Design/methodology/approach Through the introduction of the internal node, the numerical performance of the element proved to be superior to existing elements in the literature, even though a static condensation is required. Findings From several numerical examples, it is shown that convergence can be achieved with the use of only a small number of finite elements. The proposed element can be used to solve general plane linear elasticity problems resulting in excellent results. Originality/value The results obtained are comparable with those given by the robust element Q8

A new flat shell finite element for the linear analysis of thin shell structures

In this paper, a new rectangular flat shell element denoted ‘ACM_RSBE5’ is presented. The new element is obtained by superposition of the new strain-based membrane element ‘RSBE5’ and the well-known plate bending element ‘ACM’. The element can be used for the analysis of any type of thin shell structures, even if the geometry is irregular. Comparison with other types of shell elements is performed using a series of standard test problems. A correlation study with an experimentally tested aluminium shell is also conducted. The new shell element proved to have a fast rate of convergence and to provide accurate results
