During this quantity a survey of the main suitable nonlinear crack versions is supplied, with the aim of reading the nonlinear mechanical results taking place on the tip of macrocracks in quasi-brittle fabrics - corresponding to concrete, rocks, ceramics, polymers, high-strength steel alloys - and in brittle-matrix fibre-reinforced composites.

At the Lifshitz concentration (c2 = L2 = 0), a characteristic mean ﬁeld behavior S –1 (Q) ∝ Q4 appears from this equation. A realization of such a transition from S(Q) ∝ Q–2 to ∝ Q–4 is demonstrated in Fig. 24 showing S(Q) from the (PEE;PDMS) blend in a Zimm representation for three copolymer concentrations below the Lifshitz line . The solid lines represent ﬁts of Eq. 37 from which the three parameters, namely, the susceptibility S(0) and the coefﬁcients L2 and L4 are obtained. 3%, S(Q) is well described by the Ornstein–Zernike approximation with L4 = 0.
14. Both values are depicted as solid and open points which show good agreement and demonstrate consistency is always positive, and both FH parameter terms Γh and Γσ decrease with pressure. Therefore, one expects at low temperature a negative change of the critical temperature with pressure when Γh becomes the leading term. From the data in Fig. 15 one evaluates the characteristic temperatures of 14 ◦ C, 60 ◦ C, and 132 ◦ C for the dPB(1,4), dPB(1,2;1,4), and dPB(1,2) samples, respectively, below which a negative ∆P TB is expected.
A similar observation has been reported in ref. [48, 49] and will later be explained as due to the effects of thermal composition ﬂuctuations . 48 D. Schwahn Fig. 23 Phase diagram in the temperature-diblock copolymer plane for the (dPB;PS) mixture below the Lifshitz line separating blend like from diblock-like phase behavior. The full dots and the solid line represent the critical points of a two-phase region. The hatched area indicates a crossover from Ising to isotropic Lifshitz critical behavior, and a double critical point DCP is at 7% diblock concentration.
