A wind turbine blade is a long, hollow structural component made of composite material. Due to its slender nature, it is important to conduct a buckling design test to prevent such failure in service. This post illustrates how to use Ansys ACP to set up composite materials and apply them to wind turbine blade buckling … Continue reading Layered Composite Modeling using Ansys ACP – A Wind Turbine Blade

Analysis of the strength of rotor punching under centrifugal force
Rotor core punching Rotating machinery can withstand significant centrifugal force during operation. Therefore, the strength of a rotor punching should be analyzed. This problem was solved using Workbench. Considering the periodicity of the rotor punching and load, a 1/8 model was created and cyclic symmetric boundaries were defined. The model consists of a rotor punching … Continue reading Analysis of the strength of rotor punching under centrifugal force

The large deformation analysis of a hyperelastic tensile test sample
This example shows the static analysis of a tensile test sample made of rubber. The dimensions of the sample are shown in the following figure. The thickness of the sample is 1.5mm. Using the symmetry, only 1/8 of the sample is analyzed. After solving the 1/8 model, the results of the full model can be … Continue reading The large deformation analysis of a hyperelastic tensile test sample
The application of contact elements: A bolted beam-column connection
In this post, we are going to explore the application of CONTA174 (i.e. 3D 8-node face-face contact element). CONTA174 is used to represent contact and sliding between 3D target surfaces and a deformable surface defined by this element. It can be used for both pair-based contact and general contact. In the case of pair-based contact, … Continue reading The application of contact elements: A bolted beam-column connection
The application of MACRO and *DOWHILE
In this post, I will show an example of using MACRO and *DOWHILE. The APDL is developed to model an experiment as shown below. Essentially it is a clamped-clamped cracked beam carrying a body. An important feature of the body is that its mass distributes far away from its centroid, hence the rotary inertia would … Continue reading The application of MACRO and *DOWHILE
Contact analysis: a bolted flange connection
A typical bolted flange connection (see Fig.1) is modeled in this example. Fig.1. The geometry of the model. Only the 1/4 model is created due to symmetry. The challenges in this example are as follows: Complicated geometry. Applying pretension to bolts. Multiple load steps. Modeling contact. It is worth mentioning that a special element Prentension179 … Continue reading Contact analysis: a bolted flange connection
Elastic-plastic analysis of a reinforced concrete slab strengthened by a carbon fiber sheet
A reinforced concrete slab can be strengthened by adhering carbon fiber sheets to the tension side. This is a common practice in concrete structure reinforcement (as shown in Fig.1) Fig.1. Carbon fiber reinforcement. In this problem, the reinforced concrete slab is simply supported. A carbon fiber sheet is attached to the lower surface of the … Continue reading Elastic-plastic analysis of a reinforced concrete slab strengthened by a carbon fiber sheet
Wear analysis of casing coupling
Fig.1. Typical casing couplings Because the reciprocating and rotary motion of the drill pipe in the casing is eccentric, the radial and axial friction between the drill pipe and the casing causes serious wear on the outer surface of the drill pipe and the inner surface of the casing. This wear mostly occurs at the … Continue reading Wear analysis of casing coupling
