Modelling Flat Spring performance using FEA

FEA for Transient Responses of an S-Shaped Force Transducer with a Viscoelastic Absorber Using a Nonlinear Complex Spring

To compute dynamic characteristics of nonlinear viscoelastic springs with elastic structures having huge degree-of-freedom, Yamaguchi proposed a new fast numerical method using finite element method [1]-[2]. In this method, restoring forces of the springs are expressed using power series of their elongation. In the expression, nonlinear hysteresis damping is introduced. In this expression, nonl...

Analytical models are utilized to investigate the thermal performance of rectangular and disk-shaped heat pipes using nanofluids. The liquid pressure, liquid velocity profile, temperature distribution of the heat pipe wall, tempera...

Determination of Vitamin D3 in Fortified Iranian Flat Bread (Taftoon) Using High-Performance Liquid Chromatography

Background and Objectives: : Vitamin D3 measurement in food and fortified food matrixes is usually interrupted by several variables. This study aimed to elaborate a specific vitamin D3 quantification method for fortified Taftoon bread considering different influential variables in each step of measurement. Materials and Methods: Dough was fortified with (4μg/100g) and the sta...

Mass-Spring Based Point-Sampled Surface Modelling

In this paper, a physically based modelling method for point-sampled surface is proposed based on mass-spring system. First, a Delaunay based simplification algorithm is applied to the original point-sampled surface to produce the simplified point-sampled surface. Then the mass-spring system for the simplified pointsampled surface is constructed by using tangent planes to address the lack of co...
