Dear forum members! I am new member of Altair community and I am trying to model composite laminate. I created some plies with difference patches and the visualization of the different layers made me little anxious. You can see the mentioned composite layers on the attached images. The plies are symmetric in the laminate nonetheless the 3D visualization of the composite showed differences between the upper and the lower side of the composite plate. I am afraid that this kind of modeling will lead poor results. I tried to change the type of the laminate from stack to symmetric but the result was the same. How can I model the composite properly if I want to "mirror" the top half of the composite plate to the mid-plane? Somewhere I read about sub-laminates but at first look seemed complicated. I would be happy if I could solve this modeling problem easier. Thanks your answers in advance! Have a nice day! Imre.F
KTex LayUp is dedicated to representing one of the composite materials manufacturing processes: the moulding or RTM process. To do so, the fabric has to be compressed between a cast and a die. Usually, to simplify the numerical simulation, the cast and the die present very close geometries. KTex LayUp automatically creates one from the other. The user has the possibility to use any existing model of one of the two in KTex LayUp. The tool will automatically create the complementary shape and translate it before launching the simulation. The attached video is a tutorial to create a bespoke mould geometry to be sure it will be usable in KTex LayUp. KTexLayUp_Mold_creation_v2.mp4
KTex LayUp is dedicated to representing one of the composite materials manufacturing processes: the molding or RTM process. Its main objective is to automatically set-up a ready-to-run finite element model simulating this process. To do so, two input parameters are needed: the fabric and the mold. Some molds and fabrics are included in the tool database, but bespoke ones can also be created. A video regarding mold creation will come later. When selecting a fabric, two options are available: REV or Size/Shape. The REV option only needs the Representative Elementary Volume of the fabric. This REV is then duplicated and translated as many times as needed to be bigger than the mold. But the final geometry of the fabric to be molded will always be a square. The Size/Shape option needs the geometry of the fabric to be molded. This fabric can be a stack of several plies. It can feature several plies of different geometries, thicknesses or patterns... Anything is possible in order to represent the real plies that are to be molded. The user is free to define the fabric, but the user has to be careful as mistakes will not be detected. The attached video gives an example of the difference between the two options. KTexLayUp_REVvsSHAPE.mp4
