When 172.101 of this subchapter specifies that a hazardous material may be transported in accordance with this section (per special provision 148 in 172.102(c)(1)), only the bulk packagings specified for these materials in IME Standard 23 (IBR, see 171.7 of this subchapter) are authorized, subject to the requirements of subparts A and B of this part and the special provisions in column 7 of the 172.101 table. See Section I of IME Standard 23 for the standards for transporting a single bulk hazardous material for blasting by cargo tank motor vehicles (CTMV), and Section II of IME Standard 23 for the standards for CTMVs capable of transporting multiple hazardous materials for blasting in bulk and non-bulk packagings (i.e., a multipurpose bulk truck (MBT) authorized to transport the Class 1 (explosive) materials, Division 5.1 (oxidizing) materials, Class 8 (corrosive) materials, and Combustible Liquid, n.o.s., NA1993, III, as specified in IME Standard 23 (also see 177.835(d) of this subchapter)). In addition, the requirements in paragraph (a) of this section apply to: A new multipurpose bulk truck constructed after April 19, 2016; and a modified existing multipurpose bulk truck after April 19, 2016 (see 173.66(b) regarding the term modified).
From its obscure corner of the world, Delegat is on an audacious mission: to build a leading global wine exporter out of what is already New Zealand's biggest homegrown producer. The firm has moved from receivership in the 1980s to a recent market cap of $382 million. In 2015 global case sales reached 2.2 million--up 52% since 2008. The firm expects to crack the 3 million mark by 2020 (Australia's big Treasury Wine Estates, by comparison, shipped 7.6 million cases in 2015).
Abstract:This study presents a numerical model to predict the fatigue crack growth (FCG) rate in compact tension specimens under constant amplitude cyclic loadings. The material studied is the Ti-6Al-4V titanium alloy produced by selective laser melting, which was submitted to two different post-treatments: (i) hot isostatic pressing, and (ii) heat treatment. The developed finite element model uses the cumulative plastic strain at the crack tip to define the nodal release. Two different FCG criteria are presented, namely the incremental plastic strain (IPS) criterion and the total plastic strain (TPS) criterion. The calibration of the elasto-plastic constitutive model was carried out using experimental data from low cycle fatigue tests of smooth specimens. For both proposed crack growth criteria, the predicted da/dN-ΔK curve is approximately linear in log-log scale. However, the slope of the curve is higher using the TPS criterion. The numerical predictions of the crack growth rate are in good agreement with the experimental results, which indicates that cyclic plastic deformation is the main damage mechanism. The numerical results showed that increasing the stress ratio leads to a shift up of the da/dN-ΔK curve. The effect of stress ratio was dissociated from variations of cyclic plastic deformation, and an extrinsic mechanism, i.e., crack closure phenomenon, was found to be the cause.Keywords: fatigue crack growth; finite element analysis; plastic strain; Ti-6Al-4V; titanium alloy; additive manufacturing
