Features of plaxis 2d 2015 crack 365
Plaxis 2d 2015 crack 365 offers a comprehensive set of features that enable users to model and analyze various geotechnical problems in two dimensions. Some of the main features are:
Finite element analysis: Plaxis uses the finite element method (FEM) to discretize the soil and rock domains into small elements connected by nodes. The FEM allows users to account for complex geometry, material behavior, boundary conditions, loading scenarios, and construction stages. Plaxis also provides robust and efficient calculation procedures that ensure convergence and accuracy of the results.
Soil and rock models: Plaxis includes a wide range of constitutive models that can simulate the mechanical behavior of most soil and rock types. These models range from simple linear elastic to advanced nonlinear models that can capture plasticity, hardening, softening, creep, degradation, anisotropy, etc. Users can also define their own soil models using user-defined soil models (UDSM).
Groundwater flow: Plaxis can perform steady-state or transient groundwater flow analysis in saturated or unsaturated conditions. Users can define hydraulic properties of soil layers, water levels, flow boundaries, wells, drains, etc. Plaxis can also couple groundwater flow with deformation analysis to account for pore pressure changes and effective stress variations.
Thermal analysis: Plaxis can perform steady-state or transient thermal analysis in soil and rock domains. Users can define thermal properties of soil and rock layers, such as thermal conductivity, heat capacity, and thermal expansion. Plaxis can also couple thermal analysis with deformation and groundwater flow analysis to account for thermo-hydro-mechanical coupling effects.
Dynamic analysis: Plaxis can perform dynamic analysis of soil and rock domains subjected to seismic or other dynamic loading. Users can define dynamic properties of soil and rock layers, such as damping ratio, shear wave velocity, and Rayleigh damping. Plaxis can also perform modal analysis, response spectrum analysis, and time history analysis.
Plasticity and hardening: Plaxis can model the plastic behavior of soil and rock materials using various failure criteria, such as Mohr-Coulomb, Drucker-Prager, Hoek-Brown, etc. Plaxis can also model the hardening or softening behavior of soil and rock materials using various hardening rules, such as isotropic, kinematic, or combined hardening.
Interfaces and joints: Plaxis can model the interaction between different soil or rock layers or between soil or rock and structural elements using interfaces and joints. Interfaces can simulate the frictional behavior and relative displacement between two materials. Joints can simulate the cohesionless behavior and opening or closing of discontinuities in rock masses.
Structural elements: Plaxis can model various structural elements that interact with the soil or rock domain, such as beams, plates, piles, anchors, geotextiles, etc. Users can define the geometric and material properties of these elements, such as cross-section, stiffness, strength, etc. Users can also define the connection type between these elements and the soil or rock domain, such as fixed, free, or spring.
These are some of the main features of plaxis 2d 2015 crack 365 that make it a versatile and powerful tool for geotechnical engineering analysis. However, there are also some drawbacks and limitations of using this software that users should be aware of.

Example: Pile group analysis
In this example, plaxis 2d 2015 crack 365 is used to analyze a pile group consisting of four piles supporting a column load of 1000 kN. The soil profile consists of three layers: a sand layer with a thickness of 10 m, a clay layer with a thickness of 15 m, and a bedrock layer. The soil properties and the pile dimensions are given in the table below:
Soil layer Thickness (m) Unit weight (kN/m3) Young's modulus (kPa) Poisson's ratio Cohesion (kPa) Friction angle (deg) --- --- --- --- --- --- --- Sand 10 18 50000 0.3 0 30 Clay 15 20 20000 0.4 50 25 Bedrock - 25 1000000 0.25 - - Pile type Diameter (m) Length (m) Young's modulus (kPa) --- --- --- --- Concrete pile 0.5 20 30000000 The following steps are performed to model and analyze the pile group using plaxis 2d 2015 crack 365:
Create a new project and define the geometry of the model using the geometry mode. The model dimensions are set to 40 m x 40 m, and the origin is located at the center of the pile group. The pile group is arranged in a square pattern with a spacing of 3 m between piles.
Define the soil layers and assign the soil properties using the material mode. The soil layers are created using boreholes and regions, and the soil properties are assigned using material sets.

Define the boundary conditions and loading scenarios using the stages mode. The boundary conditions are set to fixed at the bottom and left boundaries, roller at the right boundary, and free at the top boundary. The loading scenarios are defined as follows: stage 1 - initial stress generation; stage 2 - application of column load; stage 3 - removal of column load.
Run the calculations and check the results using the output mode. The results include displacements, stresses, strains, forces, moments, reactions, etc. The results can be visualized in various ways, such as contours, vectors, graphs, tables, etc.
The following figures show some of the results obtained from plaxis 2d 2015 crack 365 for the pile group analysis:
Figure 1: Displacement contours of the pile group at stage 2
Figure 2: Pile load-displacement curves at stage 2
Figure 3: Pile group efficiency at stage 2
From the results, it can be seen that the pile group undergoes a maximum displacement of about 3.5 cm under the column load of 1000 kN. The pile load-displacement curves show that the piles have different load capacities and stiffnesses depending on their position in the group. The pile group efficiency, which is the ratio of the actual load capacity of the group to the sum of the individual load capacities of the piles, is about 0.8, indicating that there is some interaction and interference between the piles.

From the results, it can be seen that the sheet pile wall undergoes a maximum displacement of about 1 cm under the surcharge load of 50 kN/m2. The bending moment in the sheet pile wall reaches a maximum value of about 100 kNm/m at a depth of about 8 m. The safety factor against failure, which is calculated using the strength reduction method, is above 1.5 for the whole soil domain, indicating that the excavation is stable and safe.
