Abstract

A previous paper stated the method of determination of the neutral surface of a composite monolithic, laminate composite, organizing some of the component layers, go to the method of distribution of tasks developed in one given case. This regard illustrates several possible options of which results can enable a proper assessment of the maximum strains and alignment layers, ensuring a maximum lifting capacity. The study can be developed to optimize the organization of layers, depending on the practical purpose of using the composite structure (mechanical, thermal and / or sound).

Highlights

The minimum consumption of building materials in mechanical structures, usually, but even more in the equipment of great burden, such as those in the process industries, represent a special interest both for the researchers in the field, and for manufacturers and users
In addition to fulfilling the safety of technical regulations, the authors respond responsibly with regard to the general or specific costs as well [10,11]. It was a key reason for which in a previous work of the authors [12] it was studied the method of determining the neutral position of the surface of a laminated composite, generally with non-symmetrical alignment or a symmetrical one
In this case the sharing variants of loads allotted to component layers are exposed, for static or dynamic applications [13,14,15,16]

INTRODUCTION

The minimum consumption of building materials in mechanical structures, usually, but even more in the equipment of great burden, such as those in the process industries, represent a special interest both for the researchers in the field, and for manufacturers and users. In addition to fulfilling the safety of technical regulations, the authors respond responsibly with regard to the general or specific costs as well [10,11] It was a key reason for which in a previous work of the authors [12] it was studied the method of determining the neutral position of the surface of a laminated composite, generally with non-symmetrical alignment or a symmetrical (mirrored) one. In this case the sharing variants of loads allotted to component layers are exposed, for static or dynamic applications [13,14,15,16].
