Hi,
I am trying to find the method of stress evaluation used in Isogeometric analysis. I havn't come to know any numerical process for stress computation along with its implementation in IGA. Can someone please help me in this regard.
Thanks -Vishal
Abstract: Roll forming is a continuous process in which a flat strip is incrementally bent to a desired profile. This process is increasingly used in automotive industry to form High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) for structural components. Because of the large variety of applications of roll forming in the industry, Finite Element Analysis (FEA) is increasingly employed for roll forming process design. Formability and springback are two major concerns in the roll forming AHSS materials.
hi all,
i want to write an uel that allow me to analyse the diffusion of the moisture through a composite material (polyester/glass fiber) from two sides under two different temperatures.
any help is appreciated
Hello,
I am simulating precracked plates sujected to mixed mode I,II fatigue loading using XFEM. I managed suceed in crack propagation using static loading .However , the cyclic /fatigue loading is running but doesnt give any results? Please inform me...
Among all inspiring bio-material, Abalone seashell has its unique characteristics of high strength and toughness. Though , there is the general trend in materials that some of the toughness have been compromised for the sake of increasing hardness and vice versa. This astonishing property of sea shell attracts material scientists to understand the root cause for this property. One of such enthusiast, Prof. Kalpana Katti at North Dakota State University unlocked these secret of these phenomenon lies in its microstructure.
Hi,
Please pour in uselful tips & tricks to arrive at convergence in ANSYS workbench static structural. This for Finite Element Analysis in static structural of biomechanical components.
Thank You

Friction stir welding (FSW) has been used for joining AZ31B magnesium alloy and Al 6061-T6 aluminum alloy sheets. In this regard, the current work aims to study the mechanical, microstructural and fracture properties of dissimilar FSW welds obtained by evolving the tool rotation and translation speeds. The dissimilar welds microstructure and mechanical properties are evaluated and correlated with the FSW parameters to obtain the optimum weld conditions. The results showed that placing aluminum on the advancing side of the weld resulted in better quality welds.
Defect-free joints were friction stir welded (FSW) from AZ31 Mg alloy sheets by employing optimum welding parameters for the tool geometry used. Microstructure, texture and mechanical response of the welded joints were studied to identify susceptibility of crack initiation in the different weld zones and to understand the overall fracture behavior of these welds.
Investigated in this paper is the mechanical and microstructural response of specimens cut from rolled AA 6061-T6 alloy subjected to uniaxial loading at different temperatures (25, 100, 200, and 300 °C) and strain rates (10–4, 10−3, 10−2, 10−1 s−1). It was found that the material exhibits a strain rate and temperature dependent behavior. Microstructure observations reveal grains elongated in the loading direction with the average grain size being independent of loading conditions.
