Numerical and Experimental Investigation of an Elliptical Paraboloid Shell Model
For practical engineering purpose, a new flat shell element baptized (ACM_Q4SBE1) is presented in this paper. The formulated element can be used for the analysis of thin shell structures; no matter how the geometrical shape might be. Tests on standard problems have been examined. Since, the analysis of thin shell structures has generally been purely carried out on a theoretical basis; it is of importance to present some experimental results of an elliptical paraboloid under uniformly distributed load pressure. The results obtained from both numerical and experimental work are presented. Index Terms— Elliptical Paraboloid, finite element, flat shell element.
ANALYSIS OF STRUCTURES BY NON- CONFORMING FINITE ELEMENTS "ANALYSE DES STRUCTURES PAR ELEMENTS FINIS NON CONFORMES"
The general purpose of this thesis is to develop new finite elements based on the strain approach. In order to ameliorate the accuracy of the results, the static condensation technique has been used. Most of the finite elements developed by Sabir are characterized by a regular form and appropriate coordinates with the form of the element. To overcome this geometrical inconvenience; a new analytical integration is developed to evaluate the element stiffness matrix for the finite elements with distorted shapes. This will help to know how the elements will behave when they have irregular form, and to extend their applications domain for thecurved structures no matter what the geometrical shape of the element might be
Mentally disordered offenders and the law: Research update on the insanity defense, 2004-2019.
The insanity defense is among the most controversial legal constructs that has attracted the attention of scholars, practitioners and policy makers. Here, we conducted a systematic review of the literature spanning 2004 to 2019 that produced 58 studies of insanity defense research. Findings are organized according to: (1) assessments and assessment-related issues, (2) juror decision-making in defense trials, (3) characteristics of insanity acquittees, (4) release recommendations for insanity acquittees, (5) revocation of conditional release status of insanity acquittees, and (6) additional areas of insanity defense research. Implications of the research for the insanity defense and cognate legal issues are proffered.
