The phase field method integrates the Griffith theory and damage mechanics approach to predict crack initiation, propagation, and branching within one framework. No crack tracking topology is needed, and complex crack shapes can be captures without user intervention. In this paper, a detailed description of how the phase field method is implemented with explicit dynamics into LS-DYNA is provide...

The purpose of present study was to examine the effects of short time static and dynamic stretching of muscles on kinematics variability of lower extremity in healthy active males during cycling. 15 physical education and sport sciences male students from Kharazmi University voluntarily participated in this study. Subjects referred to the laboratory during two days, with 48 hours intervals betw...

OBJECTIVE To analyse carboplatin dosage in cancer patients in order to establish whether they are over- or underdosed in comparison to the theoretical dose calculations during the first cycle of chemotherapy and to find a relationship between the dosage in the first cycle and dose reduction in subsequent cycles, as a result of adverse effects related to the same. METHOD Retrospective analysis...

This article generalizes a proof of Steiner for the nonexistence of 1-cycles for the 3x + 1 problem to a proof for the nonexistence of 2-cycles. A lower bound for the cycle length is derived by approximating the ratio between numbers in a cycle. An upper bound is found by applying a result of Laurent, Mignotte, and Nesterenko on linear forms in logarithms. Finally numerical calculation of conve...

The task of the calculation of the dipole-dipole interaction between cobalt nanodot and magnetic tip was formalized and the computing algorithm was implemented in parallel C++ code with using of the MPI standard. The parallelization is fulfilled by means of the dividing total cycle and the passing the part of cycle in one process. Our parallel program allows obtain MagneticForce-Microscopy (MFM...

This paper presents a framework for the calculation of functional requirements at several stages of the product life cycle. It uses the TTRS/MGRE concept for the determination of dimension chains. The geometry of the assembly is represented using a parametric model constituted of points and vectors. Finally, it also integrates the calculation of part deformation due to changing operating condit...

Nonlinear time-dependent calculations are being carried out in order to study the evolution of vertically-integrated models of non-selfgravitating, transonic accretion discs around black holes. In this paper we present results from a new calculation for a high-α model similar to one studied previously by Honma, Matsumoto & Kato who found evidence for limit-cycle behaviour connected with thermal...
