1.3.8 Toughness The toughness of a material is its ability to withstand both plastic and elastic deformations. It is a highly desirable quality for structural and machine parts to withstand shock and vibration. Manganese steel, wrought iron, mild steels are tough materials. For Ex: If a load ...
After a material yields, it begins to experience a high rate of plastic deformation. Once the material yields, it begins to strain harden which increases the strength of the material. In the stress-strain curves below, the strength of the material can be seen to increase between the yield po...

Different 3D printing materials and plastic 3D printing processes have their own strengths and weaknesses that define their suitability for different applications. The following table provides a high level summary of some key characteristics and considerations. ...
An accurate model description of the effects of stress on magnetic properties of materials has become increasingly important in situations where the performance characteristics of magnetic materials, such as magnetostrictive sensors or a... L Li 被引量: 2发表: 2004年 The Effect of Plastic deformation...
ASTM D638 specifies methods for testing the tensile strength of plastics and other resin materials and for calculating their mechanical properties
Food packaging is an important concept for consumer satisfaction and the increased shelf life of food products. The introduction of novel food packaging materials has become an emerging trend in recent years, which could be mainly due to environmental pollution caused by plastic packaging and to redu...
Inspired by the gradient structures of biological materials, researchers have explored compositional and structural gradients for about 40 years as an approach to enhance the properties of engineering materials, including metals and metallic alloys. The synthesis of various gradient nanostructured materials,...
