Hybrid Composite Tensile Test

Dear Friends

Dear Engineers.

I am Master degree student and I am trying to determine Young's Modulus of Hybrid Composite. Since I Don't have any material properties in detail of each part of mentiond composite, I chose an experimental tensile test with MTS machine to attain at Least Young's Modulus. The major problem which I have faced is that due to limitation on my sample, i can just prepare specimen for transverse tensile test based on ASTM standard which recommend geometrical dimensions for specimen.

Saint-Venant's Principle: Rationalized and Rational

Submitted by Jian-zhong Zhao on Fri, 05/24/2013 - 02:46

The problem of statement of Saint-Venant's Principle is concerned. Statement of Boussinesq or Love is ambiguous so that its interpretations are in contradiction with each other. Rationalized Statement of Saint-Venant’s Principle of elasticity is suggested to rule out the ambiguity of Statements of Boussinesq and Love. Rational Saint-Venant's Principle is suggested to fit and guide applications of the principle to fields of continuum physics and cover the analogical case as well as the non-analogical case discovered and discussed in this paper .

Zanaboni Theory and Saint-Venant's Principle: Updated

Submitted by Jian-zhong Zhao on Fri, 05/24/2013 - 02:34

research

Zanaboni Theory is mathematically analyzed in this paper. The conclusion is that Zanaboni Theorem is invalid and not a proof of Saint-Venant's Principle; Discrete Zanaboni Theorem and Zanaboni's energy decay are inconsistent with Saint-Venant's decay; the inconsistency, discussed here, between Zanaboni Theory and Saint-Venant's Principle provides more proofs that Saint-Venant's Principle is not generally true.

UMAT Multi-element Issues

Submitted by nibalog on Thu, 05/23/2013 - 16:14

Hello All:

I have written a UMAT code to predict the viscoelastic behaviour within a shape adaptive structure. I have followed similar steps used in Abaqus subroutine manual, I have applied this UMAT to a single quad element and it works as predicted. But when I apply it multiple elements model it breaks down.

Is there any special command i need to put in UMAT subroutine to account multi element analysis? I will appreciate all related comments,

Thanks
