3/1/2023 0 Comments Aspect ratio calculator fem![]() ![]() A person with a 34" waist and 40" hip would therefore have a waist-hip ratio of 34/40, or 0.85. The value is calculated by dividing waist measurement by hip measurement. Waist-hip ratio (WHR) is defined as the ratio of waist circumference to hip circumference. If (hips - bust) < 3.6" AND (bust - hips) < 3.6" AND (bust - waist) < 9" AND (hips - waist) < 10" If (bust - hips) ≥ 3.6" AND (bust - waist) < 9" If (hips - bust) ≥ 3.6" AND (hips - waist) < 9" If (bust - hips) ≤ 1" AND (hips - bust) 1" AND (bust - hips) 2" AND (hips - waist) ≥ 7" AND (high hip/waist) ≥ 1.193 Also, some body shapes may not fit into any of the shapes listed below. There are very wide ranges of actual sizes within each shape. The algorithm used in this calculator is based on a study published in the International Journal of Clothing Science and Technology, which breaks down the body shapes of women into 7 categories 1. The female body shapes are based on societal standards that are subjective and are different in different cultures. This body shape (typically presented as the "ideal") describes a person with hip and bust measurements nearly equal in size, with a narrower waist measurement.Ī study of more than 6,000 women conducted at North Carolina State University in 2005 revealed that 46% of women were banana-shaped just over 20% were pear-shaped just under 14% were apple-shaped and only 8% were hourglass-shaped. ![]() Hourglass, X shape, triangles opposing, or facing inwards This body shape describes a person who has hip measurements greater than their bust measurements. This body shape describes a person who typically has waist measurements that are less than 9 inches smaller than the hip or bust measurements. This body shape describes a person who has broader shoulders and bust than they do hips. In the fashion industry, body shapes are often categorized into four classes. Hip size-the largest circumference measured around the hips over the largest part of the buttocks.įemale body shapes in the fashion industry It is around 7 inches (18 cm) below the natural waist. High hip size-the circumference of the upper swell of the hip over the pelvic region. Waist size-the smallest circumference measured around the natural waist, just above the belly button. Make sure the tape is snug against the body, but not too tight such that it compresses the body (making the measurement inaccurate).īust size-the circumference measured around the chest over the fullest part of the breasts, while wearing a properly fitted bra. Still, the weather is nice.When measuring, be sure to stand straight with arms to the side. The question was really aimed at convincing others and the probable best answer is to throw the automatic mesh generator at it, wait a week for the results, and compare results. In that respect I think the aspect ratio isn't so important providing there is little variation in the longer direction. I don't think RockEngineer's teacher is correct in saying that deformations are calculated at the element centre and then averaged out as the displacements (strains) are assumed to vary linearly in a 4 noded element, whereas the element stresses, related to de/dx, are constant, I believe. It would be possible to initally bias the mesh so that after deformation the mesh was more evenly shaped but that hasn't been tried yet. In this case it isn't general, and as Brad says, there is no choice as the material has deformed so dramatically and remeshing isn't an option. I think that in general a maximum aspect ratio of 5 to 1 is a reasonable rule of thumb for most cases away rom regions of interest. Wish I could help more but maybe this will give you some ideas. Is the region where this occurred really the region you need accurate results for.If not and you have what otherwise appears to be valid results I would not worry.Remember FEM is fundamentally an approximate method. Did the distortion decrease one direction to get the 5 x 1 ratio.If so is the integration time step reduced to account for the decreased dimension.Transit time across the element will have decreased.Ĥ. it folds to a 90 degree angle, etc.If rotational then probably will cause bad internal force computations.If extensional (either tensile or compressive) the internal force computation should be OK.ģ. Is the distortion mostly extensional as opposed to rotational i.e. The 5 to 1 ratio should not cause a problem if the stress field is linear (as you noted in the post) and if the shear is mimimal.If the shear is large then you may have a problem.Don't know where the L x W ratio becomes a problem but I have used 5 x 1 in local areas and have gotten OK results.Ģ. I am assuming since it is an explicit solution that you are using linear elements with single point integration for the internal force computation. First, You are way beyond my personal experience so the following should be taken with a large grain of salt.only responded to maybe jog your memory or suggest something that may help. ![]()
