“I can finally see clearly, all of these years I thought I knew what I was doing but I was clueless, like a snowflake floating in a winter tundra,” explained Axwell calmly.

DMT use can often lead to people having deep and profound spiritual experiences and, as in Axwell’s case, can lead to users making extreme lifestyle changing decisions. Negative applied loads are sustained by adhesion forces outside the contact.Swedish EDM star Axwell has today announced plans top quit the music industry after discovering that he was not a real DJ while taking the poweful hallucinogenic DMT.ĭMT, often described as a window into the soul, is the main ingredient in ayahuasca, a psychedelic brew used by the people of the Amazon to contact the spirit world for ceremonial or healing purposes. In the area of contact the distribution of stresses is Hertzian, and their integral is P + 27 πwR. In the DMT approximation the adhesion stresses tend toward zero to have a continuity with the stress at r = a −, but their integral is finite and the total attraction force outside the contact is 2π wR. The total attraction force outside the contact being zero, the integral of stresses in the contact is equal to the applied load P and negative applied loads are supported by the elastic restoring forces. In the JKR approximation the distribution of adhesion forces is reduced to a singular stress at r = a +. It is shown that it is not physically consistent to have tensile stresses in the area of contact and no adhesion forces outside or no tensile stresses in the area of contact and adhesion forces outside. Furthermore the value of G for the DMT approximation is derived. When λ increases from zero to infinity there is a continuous transition from the DMT approximation to the JKR approximation. The equilibrium curves a(P), a(δ), and P(σ), the adherence forces at fixed load or fixed grips, the profiles, and the stress distributions can therefore be drawn as a function of a single parameter λ. The energy release rate G is computed by the J-integral and the equilibrium is given by G = w.

This cancellation suppresses the stress singularities, ensures the continuity of stresses, and fixes the radius c and the crack opening displacement δ t. This internal loading acting in the air gap (the external crack) leads to a stress intensity factor K m, which is cancelled with the stress intensity factor K I due to the external loading. The adhesion forces are assumed to have a constant value σ O, the theoretical stress, over a length d at the crack tip.

To avoid self consistent numerical calculations based on a specific interaction model (Lennard-Jones potential for example) we have used a Dugdale model, which allows analytical solutions. On the other hand, in the Derjaguin-Muller-Toporov (DMT) approximation, the adhesion forces are taken into account, but the profile is assumed to be Hertzian, as if adhesion forces Could not deform the surfaces.

In the Johnson-Kendall-Roberts (JKR) approximation, adhesion forces outside the area of contact are neglected and elastic stresses at the edge of the contact are infinite, as in linear elastic fracture mechanics.
