“…Vallellano et al (2008) and Takuda et al (1999) found failure criteria to be good competitors compared to physically based models. They used different failure criteria to predict fracture limits of aluminum 2024-T3 and found the same limits as Lee et al (1997) and Tang et al (1999) who used a continuum ductile failure criterion. For these reasons, the emphasis of this study is put on finding criteria for predicting fracture loci and deformation levels at the onset of fracture.…”

“…The fracture strength of HA/PLLA biocomposite was determined using a stress-based criterion [23] and the scheme 3. When von Mises equivalent stress in any element of the matrix reaches a critical value, this element was considered to be in failure and removed from the model.…”

A three-dimensional finite element analysis was conducted to evaluate the feasibility of predicting the flexural properties of hydroxyapatite-reinforced poly-L-lactide acid (HA/PLLA) biocomposite using three different schemes. The scheme 1, originated from a beam analysis, was used to determine the flexural modulus analytically while the scheme 2 and 3 were designed to have different loading and boundary conditions using a finite element cell modeling approach. An empirical approach using Chow's formula and experimental data were used for comparison with the predicted results. In order to reduce the computational time and save the storage space involved in determining the effect of varying particle volume fractions on the flexural properties of HA/PLLA, a superelement technique was applied. The results using the scheme 3 and the Chow's formula were found to be in reasonable agreement with experimental results over the range of particle volume fraction. In addition to the Chow's formula, local stress distribution and the failure processes in HA/PLLA were simulated using the finite element technique.KEY WORDS composite, hydroxyapatite (HA), poly-L-lactide acid (PLLA), finite element method (FEM), cell model, flexural properties, particle volume fraction (PVF)

“…Gouveia et al (1996) evaluated four previously published ductile fracture criteria in cold bulk metal forming. Tang et al (1999) used a damage-based criterion derived by continuum damage mechanics (CDM) to predict the fracture limit of aluminum alloy Al 2024T3 sheet. Fan et al (2006) implemented an elasto-plastic constitutive equation accounting for isotropic hardening coupled with material damage to simulate deep drawing of a mild steel square cup.…”
