A study on design data and methods for plate-like injection moulded thermoplastics products

Existing methods of designing load-bearing thermoplastics, products are based upon the application of Strength of Materials formulae in conjunction with material data (E.v •••• ) obtained from simple specimens in standard tests. In injection moulding the melt flow causes the material to be oriented and consequently to become anisotropic. In this case, the application of current design methods may not predict with reasonable accuracy the behaviour of components subjected to complex states of stress... cont'd
