Material and structural behaviour of PMMA from low temperatures to over the glass transition: Quasi-static and dynamic loading

This work aims at characterizing the mechanical behaviour of polymethyl-methacrylate (PMMA) under high velocity impact conditions over a wide range of testing temperatures. To this end, the mechanical response at uniaxial compression is studied for both quasi-static and dynamic conditions covering testing temperatures below, at and above glass transition. A pseudo-brittle to ductile transition in the failure of PMMA is observed at a threshold that depends on testing temperature and strain rate. This analysis allows for the interpretation of the perforation impact tests and to explain the principal deformation and failure mechanisms. To complete the study, the Richeton model to predict yielding is revisited. Finally, we provide a new constitutive model for finite deformations to further identify the deformation mechanisms governing the mechanical behaviour of PMMA and the influence of temperature and strain rate on them.D.

CJUS 450 Women and Minorities in Criminal Justice

Course syllabus for CJUS 450 Women and Minorities in Criminal Justice Course description: Only in the last several years has the topic of female crime and criminality begun to attract attention. Patterns of criminal behavior, the etiology of female crime, and the CJUS responses with special emphasis on the correctional aspects of female offenders will be the main focus of this course in an effort to assist student to become sensitive to and aware of the relationship between women, crime, and justice. The second half of the course will deal with race, gender and justice issues

CJUS 345 Crime Causation Theories & Social Control

Course syllabus for CJUS 345 Crime Causation Theories & Social Control Course description: This is an advanced course in the criminal justice curricular sequence for all students interested in the study of crime, deviance, criminality and deviant/criminal behavior. The primary focus of the course will be the understanding of the phenomenon of crime and some of its ramifications, including a review of all prominent explanatory theories of crime and deviant behavior from a variety of approaches and schools of thought (e.g., Biological, Religious, Philosophical, Medical, Psychological, Psychiatric, Sociological, Economic and Political Science perspectives). In addition, we will examine how the philosophy, practices and programming initiatives of each era is based on the various theories of crime during that same time frame
