impact pile driving is a multi-component problem which is associated to multi-directional ground vibrations. at first, vibration is transferred from the hammer to the pile and then to the common interface of pile and soil. this is then transferred to the environment and has great impact on the adjacent structures, causing disturbance to residents and also damage to the buildings. it is of high ...

Subsea pipelines and cables placed in ice-prone regions may be at risk of iceberg damage. In particular, pipes that are not buried come direct contact with keels. Knowing the range interaction forces helps to assess types magnitudes potential Experimental studies provide most valuable data about forces, while numerical modeling give insight into configurations difficult study experimentally. Th...

hydromechanical deep drawing (hdd) is one of the most convenient processes in which a sheet metal is drawn against a counter pressure rather than a rigid die in conventional stampings. this process has been increasingly used to produce aerospace and automotive components. more recently, aerospace industry is demanding new materials with capability to produce high strength to weight ratio produc...

Women are interested to wear high-heeled shoes to increase their attractiveness. High-heeled shoes might create harmful effects on the musculoskeletal system. Besides earlier studies proved that the function of foot and lower extremity will change due to wearing highheeled shoes [1,2]. Because of limitations of the experimental methods, direct measurements of internal strains and stresses of th...
