Hello guys,<\/p>\n
I’ve got a tube composed of composite material that consists of a stainless steel coil covered by two layers of identical TPU (both from inner and outer diameter), in which the material properties of the TPU is to be determined.<\/p>\n
The idea is to temporarily substitute material properties of the softest generic TPU found on the MatWeb, make an identical real-life and simulation setup to measure the deflection of the tube under a given loading, and then fine-tune the forementioned TPU material properties until the results from both scenarios agree with each other.<\/p>\n
It should be noted that the tube itself is straight but is (and will be) bent and fixed at both ends in each scenario, because it is rather soft and will deflect by a lot even with minimal loading. By pre-bending the tube we should be able to make it stiffer and get more repeatable result.<\/p>\n
It should also be noted that there is a small cut-out at the middle of outer TPU layer from the top, in which 10 MPa of pressure is applied on a 4 mm² face, which implys that the tube is subjected to a 40 N load. However, the result shows that the maximum deflection is about 8 mm occured at the middle, which deemed unreasonable for such a soft structure even after taking the pre-bending and coil reinforcement into account. So I wonder if there are settings that I have overlooked, or if I have made some wrong settings in the first place.<\/p>\n
I have also attached a link to my .wbpz file below. Any help would be greatly appreciated.<\/p>\n
