Effect of circular holes on the ratchet limit and crack tip plastic strain range in a centre cracked plate [PDF]
, 2011 In this paper a centre cracked plate subjected to cyclic tensile loading and cyclic bending moment is considered. The effect of circular holes drilled in the region of the crack tip on the ratchet limit and crack tip plastic strain range is studied ...

Revista Brasileira de Ciência do Solo, 2006 A susceptibilidade do solo à compactação, avaliada pelo ensaio Proctor, torna-se menor à medida que cresce a quantidade de material orgânico existente. Em geral, para um mesmo nível de energia, quanto maior o teor de matéria orgânica do solo, menor é o ...

Plastic Waste: Environmental Legal Issues and Policy Law Enforcement for Environmental Sustainability [PDF]
E3S Web of Conferences, 2021 The use of plastic products has been part of human life and daily activities. Since plastic can be harmful to the environment, solutions are required to limit, reduce, and minimize the use of this material for sustaining environmental preservation ...

Plastic load evaluation for a fixed tube sheet heat exchanger subject to proportional loading [PDF]
, 2012 The plastic load of pressurised components can be calculated based on both the twice elastic slope and tangent methods. Both methods are problematic since they rely on parameters that are localised and therefore have a strong dependency on the gradient ...
