An attempt to predict the buckling time was made using the isotropic creep equation with Mises stress potential as outlined above for the plastic liner in the warpage problem.

Issues related to HE of steel liner may still exist however, due to the thin steel liner carrying lower stresses, potential for hydrogen cracking could be reduced. 

For one of our carbons we estimate that in some cases < a and C are of the order of 20% of the adsorption potential, assuming a Poisson ratio of 1/3. In these cases one may regard the adsorption potential as arising from a release of a compressive stress potential (80%) and a shear strain potential (20%).

Generally, a heavy breakfast (approximately 1000 calories and 50 percent of the energy content from fat) should be used, since this is supposed to stress potential food effects. A proposal for a standardised composition of a heavy breakfast is displayed in Table 7.4 (FDA 1997c).

Banabic et al. (2005) proposed a new expression of the plane stress potential. An improvement of this criterion has been implemented in the finite element commercial code AUTOFORM version 4.1 (Banabic and Sester 2012). The equivalent stress is defined by the following formula ...

Item 2 indicates that a cool down time is allotted so that the latent heat of the oven does not create a heat exposure hazard. We concur with the cool down practice to eliminate this heat stress potential. However, we suggest the actual job safety practice indicate a maximum oven temperature allowable or other measurable parameter (period of time) allotted before entry. 

Another popular and useful approach for many practical engineering problems that can be reduced to two dimensional plane strain or plane stress approximations involves an auxiliary stress potential. In this approach, a bi-harmonic equation is developed based on the stresses (in terms of the potential) satisfying both the equilibrium equation and the compatibility equations. The result is that stresses derived from potentials satisfying the biharmonic equation automatically satisfy the necessary field equations and only the boundary conditions must be verified for any given problem. A rich set of problems may be solved in this manner and examples can be found in many classical texts on elasticity. In conjunction with the use of the stress potential, the principle of superposition is also often invoked to combine the solutions of several relatively simple problems to solve quite complex problems. 

Since the fiber reinforcement grants composites increased strength, it also make them sensitive to temperature and moisture stress, presence of chemical pollutants, etc. During their service time, addition of tensile stress potentiate the negative effect of the weathering, but compressive stress may reduce the propagation of some degradative processes [101]. 

Assuming that there exists a stress potential Z = 2( 1 ), we find that the constitutive equations for an isotropic (isothermal) micropolar elastic solid are given, up to quadratic terms in strain measures, in Cartesian tensor notation [9] ... 

Figure 5.3 Schematic illustration of an SGR-type model of plastic deformation in amorphous media. Deformation occurs via elastic deformation, localized plastic events (in the regions represented by boxes), and nonlocal redistribution of the elastic stress, potentially triggering other plastic events.

Injection molded parts are known to degrade under the influence of UV or chemical environment (environmental stress cracking) at certain areas of stress concentration. Release agents may play certain role in these processes because they may help to release part before its core has solidified. Also, uneven distribution of release agent on surface may induce tension into a part skin. Any internal stress potentially increases risk of material degradation, under the influence of radiation or contact with solvents. The essential parameters, which contribute to stress formation, are evaluated in a broad research study. ...
