Product support during EOL varies by product. Different lifetime examples include toys from fast food chains (weeks or months), mobile phones (3 years) and cars (10 years). The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view. All users can continue to access discontinued products, but cannot receive security updates and technical support. In the specific case of product sales, a vendor may employ the more specific term " end-of-sale" (" EOS"). The vendor may simply intend to limit or end support for the product.
#DEFINE LIFING SOFTWARE#
At this stage, a vendor stops the marketing, selling, or provisioning of parts, services, or software updates for the product. Element stress tensor sequences can be also filtered with the Multiaxial Racetrack Filter.Milestones in a product life cycle: general availability (GA), end of life announcement (EOLA), last order date (LOD), and end-of-life (EOL)Īn end-of-life product ( EOL product) is a product at the end of the product lifecycle which prevents users from receiving updates, indicating that the product is at the end of its useful life (from the vendor's point of view). 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, Narrow Band or Stainberg methods. Multiaxial analysis with equivalent stresses Multiaxial analysis with Dang-Van, McDiarmid, generalized Goodman. When LIFING is installed the MIL-HDBK-5J S-N curves database is installed.
