With the goal of ensuring security passengers for automotive industry, present work addresses temperature and impact speed envelope allowing ductile failure plasticized PVC to be obtained. A database about 250 test results has been constructed various conditions at ten temperatures, four speeds two specimen geometries (with or without scoring). The desired was characterized by shape load versus...

The crossdie test, i.e. deepdrawing with cross shaped tools, is used in industry to asses the formability of the sheet material. The strain path of the material in this test is non-proportional. The effect of strain path changes can be modelled with the Teodosiu & Hu model. Therefore this model is applied to describe the Bauschinger and cross hardening effects present in the crossdie test to im...

Neck retardation in stretching of ductile materials is promoted by strain hardening, strain-rate hardening and inertia. Retardation is usually beneficial because necking is often the precursor to ductile failure. The interaction of material behavior and inertia in necking retardation is complicated, in part, because necking is highly nonlinear but also because the mathematical character of the ...

*Correspondence: Davide Bigoni , via Mesiano 77, Trento I-38123, Italy e-mail: [email protected] A model of a shear band as a zero-thickness non-linear interface is proposed and tested using finite element simulations. An imperfection approach is used in this model where a shear band that is assumed to lie in a ductile matrix material (obeying von Mises plasticity with linear hardening), is p...

Prediction of service life of ductile iron pipe is carried out using the information on pipe condition, backfill/soil properties, and corrosion rates, as well as historical failure records. Among the factors that affect pipe condition, external pitting corrosion is a prominent variable contributing to the disintegrity of the pipe. A pipe scanner equipped with a laser displacement sensor was use...

Abstract In this work, the phase-field approach to fracture is extended model fatigue failure in high- and low-cycle regime. The energy degradation due repeated externally applied loads introduced as a function of local accumulation variable, which takes structural loading history into account. To end, novel definition variable proposed, allowing analysis at monotonic without interference exten...

This paper addresses a detailed analysis of the ice–structure interaction process phase-locked ice crushing (PLC) against offshore structures. Directly measured load, structure response data, and in situ observation from field measurements on Molikpaq lighthouse jacket platform were used study. summarizes new ductile damage-collapse (DDC) failure mechanism for PLC process. The DDC shows that is...
