This paper presents the object oriented approach to programming the finite element method using the Java language. The developed finite element code consists of ten Java packages. Three main methods are related to generation of finite element models, solution of elastic and elastic-plastic boundary value problems, and visualization of models and solution results. Objectoriented model of the cod...

time-history analysis is defined as a kind of dynamic analysis increasingly used in design of structures and evaluation of existing ones. one of the important issues in the time-history analysis is selecting earthquake records. in this case, seismic design provisions states that time histories shall have similar source mechanisms, geological and seismological features with region under study. a...

Introduction: Cycloidal crack patterns on Europa are influenced by tidal stress [1]. A wellrecognized portion of the tidal stress is associated with Europa’s orbital eccentricity, which in turn is driven by the Laplace orbital resonance. Their shapes record the location of their formation, as well as the conditions for crack formation. Hoppa et al. modeled several cycloid chains [2]. Hurford et...

For narrowing with a set of rules ∆ modulo a set of axioms B almost nothing is known about terminating narrowing strategies, and basic narrowing is known to be incomplete for B = AC. In this work we ask and answer the question: Is there such a thing as an extremely terminating narrowing strategy modulo B? where we call a narrowing strategy S enjoying appropriate completeness properties extremel...
