“…Such a step is used for a stress/displacement analysis with a time dependent material response. The VISCO procedure implements time integration of the material behaviour in consecutive temporal increments (Aydiner et al, 2005). To account for geometric non-linearity due to distortion of the mesh the NLGEOM option was used.…”

A critical stress at a critical distance crack propagation criterion is a good way to model the fracture in cheese. This physical criterion states that the crack-tip node debonds when the stress at a specified distance ahead of the crack tip on the assumed crack path reaches a critical value. Although this criterion is already used in other research domains, no consistent information exists on how the critical stress and distance should be determined. A repeatable method for the determination of this criterion which combines experimental and numerical single edge notched bending tests was acquired. This criterion was validated with wire cutting experiments of cheese. The experimental and numerical results showed the same trend with a clear wire indentation and steady state cutting phase. The determination of a critical stress and distance criterion as proposed in this research is a good approach to model fracture and cutting of cheese

“…While there are many ways to measure residual stress from monochromatic X-rays, neutrons, polychromatic X-rays, and nano-indentation [1,2,3,4,5], one convenient method for measuring stresses in optically transparent birefringent parts is photoelasticity. Using cross-polarized light, fringes proportional to the stress state can be observed.…”

Efficient manufacturing requires consistency. Automated equipment is designed to accept a small range of input variability and quickly sort and process for next steps. A case study for injection molding of polyethylene terephthalate preforms for use in stretch-blow molding was presented. One convenient method for measuring stresses in optically transparent birefringent parts is photoelasticity. Using cross-polarized light, fringes proportional to the stress state were observed. Faster cooling improved the residual stress state in the injected preforms. The improvements were both in magnitude, as represented by the frequency of fringes and consistency, as represented by the improved symmetry of the fringes. Lower pressure in the mold also aided in improving the residual stress state. Reducing the pressure needed to inject was accomplished by increasing the vent width.

“…They include: degradation of soft-magnetic properties [1][2][3][4][5][6] and of dimensional stability on cooling [7,8]; interference with measurements of fracture toughness [9] and hardness [10]; and prevention of the inference of density changes from length measurements [11]. On the other hand, strengthening of bulk metallic glass (BMG) composites has been attributed to tensile residual stresses in the BMG matrix [12].…”

“…Residual stress distributions in as-cast BMG samples have been extensively studied [7,8,13]. Through the thickness of a plate, the stress variation is roughly parabolic, with surface compression balanced by internal tension, just as in thermal tempering of conventional oxide glasses [14].…”

A plate of bulk metallic glass Zr 55 Ti 5 Al 10 Cu 20 Ni 10 , shot-peened on both faces, has been studied by synchrotron X-ray diffraction in transmission. The ellipticity in the first diffraction halo changes throughout the plate thickness. The elastic strain in the plate interior is measured and the compressive stress profile in the peened surfaces is estimated. Structural anisotropy and dilatation induced by plastic deformation preclude direct measurement of the elastic strain in the peened layers. Plastic deformation induces softening, but changes in the elastic properties remain undetermined.
