Micro-Blast Waves
(2014-09-02)The near field blast–wave propagation dynamics has been a subject of intense research in recent past. Since experiments on a large scale are difficult to carry out, focus has been directed towards recreating these blast ... -
Studies On Fatigue Crack Propagation In Cementitious Materials : A Dimensional Analysis Approach
(2014-08-19)Crack propagation in structures when subjected to fatigue loading, follows three different phases namely - short crack growth, stable crack growth and unstable crack growth. Accurate fatigue life prediction demands the ... -
Novel Suspension Mechanisms For A Three Wheeled Mobile Robot Traversing Uneven Terrains Without Slip
(2014-08-12)A wheeled mobile robot (WMR) will move on uneven terrain without slip if the length of the axle connecting two wheels can change or for a fixed length axle the wheels are allowed to tilt in a lateral direction. In this ... -
Kinematic And Dynamic Modeling Of Human Walking
(2014-08-07)Walking comes naturally to us and appears to be simple. However, this is not so and it is known that walking requires high level neural control and muscle coordination. There is no single, unifying theory of bipedal walking. ... -
