I’m not saying that I have all the answers or that I’m going to single handedly end global warming. How can we truly change if we don’t see the problems with ourselves and the wrong-doings that have come from our past? What’s the point of hiking for five months if I just go back to wishing there was more being done for the “endangered” environment, yet doing nothing about it within my own life? The trail inspires, but in order to do that, hearts must be broken. As I walk along the trail, I wonder PCT-inspired thoughts such as, why is there not MORE wilderness? Why is this area not protected from logging? How many more times can the soil take another clear-cut? Why are there no fish in this lake? How could we have shot the last Grizzly bear in California in the 1920’s? The wild, ancient, and ever living PCT is inspiring a break in my heart that is meant to trickle into my life. And by “The PCT,” I mean those who hike her (past present, and future), the creatures who live all along her, and the God who formed her mountains, streams, and all that’s in between. The PCT is breaking my heart with the things that break her heart. The PCT will break your heart, that I understand completely, but not in a “this will never last” sort of fairy tale way, but in a good way. Wandering and without adventure.īut the more I get to know the PCT, the more I understand that statement, or at least what that statement means in my case. I guess I always perceived that statement to mean the following: The PCT is like a “summer fling” – she’ll show you places you’ve never dreamed of before, give you butterflies in your stomach, and whisper “sweet nothings” in your ear…and then…she’ll leave you cold and dry. I read her entire blog around the time Dan and I decided we were going to do this hike, and that phrase stuck with me. Element stress tensor sequences can be also filtered with the Multiaxial Racetrack Filter.Those are some final thoughts I read on Carrot Quinn’s blog, a thru-hiker from 2013. The option to dump the counted sequence in AFGROW format is available.Įxceedence plots and Range-Mean Hystograms can be visualized The output cycles sequence is dumped in a ASCII file. The Range-Pair method is implemented as per the ASTM STP1006 standard. ![]() Offsetting (entire sequence or a portion)Ĭycle counted. Non-turning points filtering (always active) This module allows to perform the following tasks.įilter sequence. Time histories can be exported and/or handled as following: Multiaxial Assessment can be performed (scatter plots for showing Maximum Principal direction variation over the time as well as Biaxiality ratio variation over the time. ![]() Mohr Circles at defined instant can be visualized The sequence of stress tensors can be visualized and dumped in ASCII files The analyst can put on any FEM location (on the surface), a strain gauge and can orient it. Other than just analysing, the LIFE module can be used for stress tensor time history extraction at selected locations with Virtual Strain Gauge and related Multiaxial Assessments. The user can import a set of sequence files coming from a real strain gauge (uniaxial or 0-45-90 or 0-60-120 or 0-120-240): as for the above, the fatigue analysis can be therefore carried out with any of all implemented methods. The user can import a stress tensor file, instead of a FEM model: in this case LIFE creates a single element database where internal stresses are those imported from the file and fatigue can be calculated at this element with any of all implemented methods. The user can import a sequence file, instead of a FEM model: in this case the sequence is recognized as a stress sequence and the user can perform a uniaxial fatigue analysis with any of all implemented methods. LIFE can also be used for 'straight analyses': Multiaxial analysis with uniaxial reduction (critical plane search)įatigue based on PSD is handled: some load channels can be 'fed' with PSD signals and equivalent time histories are calculated with the Dirlik or Narrow Band methods. ![]() Multiaxial analysis with equivalent stresses, such as Sines Multiaxial analysis with Dang-Van, McDiarmid, generalized Goodman. When LIFING is installed the MIL-HDBK-5J S-N curves database is installed. ![]() S-N curves as per MIL Standard (MIL-HDBK-5J). Multiaxial Elastic-Plastic Stresses calculated with Dowling or Hoffman-Seeger approach by reducing the generic Non-proportional Loading cases to Proportional Loading ones or by using full Multiaxial Non-Proportional Loading cases with Pseudo-Material approach in conjunction with the Mroz-Garud cyclic plasticity model.Ĭritical Plane methods are implemented. The following analysis methods are available.Įlastic-Plastic Stress calculation with Neuber or E.S.E.D.
