Since dynamic loading problems are very difficult as compared to their static counterpart, relatively little is known about dynamic behavior of heterogeneous materials and structures. Topics covered include the response of metallic, ceramic as well as polymeric composite materials to blast and shock loadings, impact loadings and failure of novel materials under more controlled dynamic : Paperback.
The dynamic behavior of materials is a subject of ever- increasing interest to the tec hnical community owing to appli- cations ra nging fro m shock and bl ast to crash, impact and.
The paper describes experimental and computational testing of regular open‐cell cellular structures behaviour under impact loading. Open‐cell cellular specimens made of aluminium alloy and polymer were experimentally tested under quasi‐static and dynamic compressive loading in order to evaluate the failure conditions and the strain rate sensitivity.
Impact load tests were performed using a steel mass of kg. The free fall height was varied from 1 – 2 m. The peak impact load varied from – kN, without any clear correlation with the height.
The corresponding impulse load varied from – kNs with a clear correlation to the height. All slabs subjected to impact load. International Conference on Impact Loading and Dynamic Behaviour of Materials ( Bremen, Germany).

Impact loading on concrete gives rise to a strain rate influence on strength, stiffness, ductility and failure mode. Moreover, inertia is activated, which influences the resistance and failure mode of concrete structures.

Brittle materials, such as ceramics, rocks, glass and concrete, are widely used in many civil and military applications involving dynamic loading, impulse loading, and shock or impact.
In the introduction of the book Dynamic behaviour of materials, it is worth noting that among the examples of ‘applications where high-strain-rate phenomena are important’ that are given to illustrate the need for investigating materials under dynamic loading.
The purpose of this review is to discuss the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials. The review begins by briefly introducing the history of rock dynamics and. Impact loading and dynamic behaviour of materials.

The differences between impact and quasi-static behavior are mainly due to three factors   : a) inertia forces under dynamic loading lead to a time-dependent distribution of sectional.

Dynamic loading of the samples through impact provides a fiducial (at the time of the impact) from which the time-dependent response of the material can be measured. Similar to quasi-static experiments, the boundary condition on the sample provides a single loading direction, and the resulting material response can be measured.

Fig.1b. Load-time plots under dynamic loading . For even higher rates, the impact response curve concept has been developed in Germany (e.g. Ref 5) and the calibrated crack tip strain gauge method has been developed in the UK  and the USA .The overall principle of the latter is essentially to turn the specimen into its own load cell.
An Introduction to Shock, Impact, and the Action of Viscoelastic Materials Shock is a stimulus applied to a system. A mechanical shock is a sudden acceleration or deceleration. A drop, strike, kick, earthquake or explosions are examples of shock.
The term shock is used to describe matter that is subjected to force with respect to time. The. parentheses is the dynamic amplification–the factor by which a load is amplified when suddenly imposed.
Since the displacement and load are proportional the effective force carried by the beam during impact is the product of the dynamic amplification and the weight, W. Note that the dynamic amplification for V = 0 (Ek = 0) = 2: a load suddenly.
6Elasticity is a form of materials response that refers to immediate and time-independent deformation upon loading, and complete and instant recovery of the original geometry upon removal of the load.
A material is elastic or it is not, one material cannot be “more elastic” than another, and a material can be elastic without obeying the. Mechanics of Materials, a journal in the field of solid mechanics and materials, aims to disseminate quality research work in the broad spectrum of engineering and natural materials.
