CADWIND – the world’s most sophisticated filament winding software
CADWIND
- simulates based on a physical model the winding process on the computer
- calculates the fibre path and winding pattern for any mandrel geometry
- automatically generates the part program in order to produce the part on any filament winding machine or robot
- can export the calculated laminate structure to a FEA (Finite Element Analysis) software so that the mechanical characteristics of the part can be calculated immediately
With CADWIND you can make the most of filament wound composite materials, optimize the winding process, save material costs and achieve shorter production times.
CADWIND is the result of over 30 years of research and development and has proven itself in a large number of winding projects and applications time and again. Components manufactured with CADWIND can be found everywhere: on land, at sea, deep underground, at the bottom of the oceans, in the air, in space and even on planet Mars.
Laminate load response
Laminate loads consist of external mechanical loads and internal thermal or hygroscopic loads. In order to solve real-world problems, COMPOSITE STAR defines a constant and a variable load. Typically the constant load is a preload (e.g. thermal loads resulting from curing, an external static mechanical load). The variable load is used to define a dynamic external mechanical load. This permits the calculation of the extent to which the dynamic external load can be increased until failure occurs.
Failure criteria
COMPOSITE STAR uses the ply-by-ply failure analysis in its most modern and advanced form. Besides the standard failure criteria (maximum stress, maximum strain, simple Puck, modified Puck, Tsai-Hill, Tsai-Wu, Hoffman, Hashin), COMPOSITE STAR introduces one of the world’s most detailed and sophisticated interactive criterion, Puck’s action plane criterion. This criterion distinguishes between the different fracture modes (tensile and compressive fiber-fracture, tensile, shear and compressive inter fiber fracture), calculates the fracture plane angle for inter-fiber fracture and can predict catastrophic wedge effects.
