An integrated study on the optimal shape design of cruciform specimen used in equibiaxial tensile test of a hyperelastic material

, 2017
To conduct a finite element analysis of a material exhibiting large deformations (hyperelastic material), hyperelastic Ogden model is commonly used. However, hyperelastic Ogden model requires several tensile tests data including equibiaxial tensile test ...

Surrogate-Based Shape Optimization of a Cruciform Specimen for Biaxial Testing of Microparticle Reinforced Epoxy Adhesives

Applied Sciences
Reliable determination of the in-plane biaxial mechanical behavior of particle-reinforced composite adhesives under multiaxial stress conditions requires cruciform specimen geometries that achieve high stress uniformity in the measurement zone.

Determination of instability of a DP 980 steel sheet under different stress states based on experiment and theoretical models

MATEC Web of Conferences, 2016
It is generally accepted that the formability of sheet metal is limited by the onset of instability which can be described by forming limit diagram (FLD) in ε1-ε2 space.

A Thermo-Mechanical Coupled Gradient Damage Model for Heterogeneous Rocks Based on the Weibull Distribution

Energies
This study develops a thermo-mechanical damage (TMD) model for predicting damage evolution in heterogeneous rock materials after heat treatment. The TMD model employs a Weibull distribution to characterize the spatial heterogeneity of the mechanical ...
