This book puts forward a unifying perspective to combine existing theories involving the higher order gradient of the strain tensor, or of plastic strain. It begins by reviewing experimental findings on the existence (or non-existence) of size effects on the mechanics of materials. In turn, the book devises first, second and higher order strain gradient theories from general principles, and presents constitutive frameworks that satisfy thermodynamic requirements. The special case of strain gradient plasticity is then developed and illustrated via computational analyses of size effects on the plasticity of metals at small scales. In closing, the book explains the origin of gradient effects in the case of lattice structures by drawing on homogenization theory. . | | 出版日期 | Book 2020 | | 关键词 | gradient materials; strain gradient; non-local mechanics; gradient plasticity; disclocation density tens | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-030-43830-2 | | isbn_softcover | 978-3-030-43832-6 | | isbn_ebook | 978-3-030-43830-2Series ISSN 0254-1971 Series E-ISSN 2309-3706 | | issn_series | 0254-1971 | | copyright | CISM International Centre for Mechanical Sciences, Udine 2020 |
