A new plastic-damage constitutive model applicable to lightweight concrete (LWC) and normal weight concrete (NWC) is proposed in this paper based on both continuum damage mechanics and plasticity theories. Two damage variables are used to represent tensile and compressive damage independently. The effective stress is computed in the Drucker-Prager multi-surface plasticity framework. The stress ...

This paper describes the technological process for waste IC components reuse and studies its effect on the reliability of plastic IC components through some experiments. Results show that the high temperature thermal shock during printed circuit board (PCB) disassembly and appearance repair could lead to interfacial delamination and subsequent popcorn cracking in plastic IC packages. In the end...

ISSN 2277-5056 | © 2012 Bonfring Abstract--The workability of fresh concrete should be characterized by its rheological properties based on material science approach to overcome the inadequacies of traditional empirical tests like slump test. Generally the rheological properties of fresh concrete are described by Bingham parameters in terms of two physical quantities, namely yield stress and pl...

The population of our country is increasing rapidly and due to it plastic waste is also increasing day to day due to urbanization, development activities and changes in life style, which leading extensive environment pollution. Thus disposal of waste plastic is a threat and become a serious problem globally due to their nonbiodegradability and anaesthetic view. Since these are not disposed scie...

This document is the second deliverable produced within WP2 in the PLASTIC project. This deliverable describes the PLASTIC UML2 profile that concerns the starting point of the whole PLASTIC development process (described in PLASTIC Deliverable D2.1 – http://wwwc.inria.fr/plastic/deliverables/plastic-d2_1-finalpdf.pdf/download). It is a concrete implementation of the PLASTIC conceptual model (de...

Shape memory alloys (SMAs) are unique smart materials that have many advantages, such as ability to resist large strains without leaving residual strains and ability to recover original form. However, the high costs of SMAs have limited their usage. This paper evaluates the behavior of concrete structures equipped with SMAs in an optimal manner as they are being used along the plastic hinge of ...
