High Accessibility Cabinet Insert, Matthew Leal

All Undergraduate Projects

Watching grandparents and parents get older, the struggle of day-to-day activities generally increases. One of the most recurring issues the older generation experiences nearly daily is their inability to reach dishes, glassware, and other things on the topmost shelves of a kitchen. Not only is it difficult for them to use things such as stepstools, it also becomes increasingly dangerous. With age, a fall from any height could be catastrophic. With this scenario in mind, a user-friendly cabinet insert would be a very effective way to combat this issue. However, many existing models of cabinet designed to fit these requirements …

Progressive Failure Analysis Of Composite Materials Using The Puck Failure Criteria, Karan Kodagali

Theses and Dissertations

Fiber reinforced composites have been used in various engineering structures and applications especially in naval, automotive, aeronautical and sports industries. These composite materials generally exhibit brittle damage behavior. The anisotropy in the material and different kinds of failure mechanisms make it difficult to accurately characterize the behavior of composite materials. The present work aims to verify and apply the Puck Failure Criteria using the commercially available finite element package ABAQUS by writing a user-material subroutine in FORTRAN. The model is implemented with different post failure degradation schemes.

In the present work, the progressive failure on composite materials in analyzed using …
