Very few polymer mechanics problems are solved with only pen and paper today, and virtually all academic research and industrial work relies heavily on finite element simulations and specialized computer software. Introducing and demonstrating the utility of computational tools and simulations, Mechanics of Solid Polymers provides a modern view of how solid polymers behave, how they can be experimentally characterized, and how to predict their behavior in different load environments. Reflecting the significant progress made in the understanding of polymer behaviour over the last two decades, this book will discuss recent developments and compare them to classical theories. The book shows how best to make use of commercially available finite element software to solve polymer mechanics problems, introducing readers to the current state of the art in predicting failure using a combination of experiment and computational techniques. Case studies and example Matlab code are also included. As industry and academia are increasingly reliant on advanced computational mechanics software to implement sophisticated constitutive models - and authoritative information is hard to find in one place - this book provides engineers with what they need to know to make best use of the technology available.

With contributions from experts from both the industry and academia, this book presents the latest developments in polymer products and chemical processes. It incorporates appropriate case studies, explanatory notes, and schematics for more clarity and better understanding.

This books studies syntax of NPIs and their interaction with sentential negatives in Hindi. It outlines the clause structure of Hindi and locates the syntactic position of sentential negatives as well as constituent negatives within the structure. It is argued that sentential negative in Hindi negation marker heads its own maximal projection, NegP, which is immediately dominated by TP. In addition to locating the position of negation markers in the clause structure, it outlines the distribution of negative polarity items (NPIs) in Hindi and the structural constraints on their licensing by sentential negative. The book argues that an NPI in Hindi is licensed overtly in the course of derivation by a c-commanding negative marker. The bulk of the evidence presented in this book argues against previous theoretical accounts that claim that NPI licensing involves covert syntactic operations such as LF movement or reconstruction. With respect to the classification of NPIs , this book also shows the existence of two different types of NPIs in Hindi; namely, strong NPIs and weak NPIs. Strong NPIs require a clause mate c-commanding negative licensor, whereas weak NPIs are quantifiers and are similar to free choice 'any' in English that are interpreted as NPIs in the presence of a c-commanding negative licensor.
