Book Description
An experimental investigation was performed on dynamic compressive stress-strain relationships for steel fiber reinforced concrete (SFRC) with various steel fiber volumetric contents under cyclic compression at a medium strain rate. Results indicate that the mechanical properties of SFRC are not only affected by strain rates but are also influenced by loading modes. The envelope curves of unconfined SFRC are different from those of specimens under monotonic compression. Dynamic compressive strength presents a non-monotonic enhancement with increasing steel fiber content. On the basis of the experimental results of cyclic compression at a medium strain rate, the elastic-plastic damage constitutive equations are proposed to describe the dynamic compressive stress-strain relationships of SFRC under cyclic compression at a medium strain rate. These equations match the test results well.

Book Description
This text presents advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory.

Book Description
Dry granular materials, such as sand, sugar and powders, can be poured into a container like a liquid and can also form a pile, resisting gravity like a solid, which is why they can be regarded as a fourth state of matter, neither solid nor liquid. This book focuses on defining the physics of dry granular media in a systematic way, providing a collection of articles written by recognised experts. The physics of this field is new and full of challenges, but many questions (such as kinetic theories, plasticity, continuum and discrete modelling) also require the strong participation of mechanical and chemical engineers, soil mechanists, geologists and astrophysicists. The book gathers into a single volume the relevant concepts from all these disciplines, enabling the reader to gain a rapid understanding of the foundations, as well as the open questions, of the physics of granular materials. The contributors have been chosen particularly for their ability to explain new concepts, making the book attractive to students or researchers contemplating a foray into the field. The breadth of the treatment, on the other hand, makes the book a useful reference for scientists who are already experienced in the subject.
