Unsaturated Seepage Analysis of Cracked Soil including Development Process of Cracks

Probabilistic analysis of weld cracks in center-cracked tension specimens

This paper describes the development of a probabilistic methodology for fracture-mechanics analysis of weld cracks in a center-cracked tension (CCT) specimen. It involves elastic±plastic analyses to predict J-integral, statistical models of uncertainties in loads and material properties, and standard computational methods of structural reliability theory for probabilistic analysis. Eighty-one d...

Earthquake Analysis of Base Isolated Structures Including Soil-Structure Interaction

A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
