In 1925 it was a tremendous effect that “ Father of Soil Mechanics” published his first soil mechanics book. Within a short span of about 20 years, after publishing his first book, it has been seen that there was a new specific area needed. Karl Terzaghi

Dynamic loads are imposed on soils and geotechnical structures by several sources, such as earthquakes, blasts, machinery, operations of constructions, traffic, mining, wind and wave actions. It is well known that the stress strain properties of a soil and its behaviour depend on several factors and may different in many ways under dynamic loading conditions as compared to the case of static loading. Soil dynamics is the branch of soil mechanics, that deals with the behaviour of soil under dynamic load, including the analysis of the stability of earth supported and earth retaining structures .

As thought in the static conditions, under dynamic conditions, the soil must be investigated in two ways. Obtaining of soils dynamic properties is important to investigate the response of it, under earthquake or cyclic loads. Under cyclic loads, with undrained conditions; general strength failure, liquefaction at cohesionless soils and deformations and failures at cohesive soils must be analyzed. Soil behaviors under dynamic loads must be investigated about strength and stress strain charactheristics.

A typical stress strain hysteresis loop. As a properties of stress strain characteristics; dynamic shear modulus, damping ratio and the relationship of those with shear deformation is considered. As a properties of strength; the maximum shear stress amplitude that causes the failure and the cycle numbers are must be thought.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
